Obesity in dogs is associated with various health issues such as diabetes, heart disease, and arthritis. Engaging in activities like walking, running, and playing not only burns calories but also improves cardiovascular health, strengthens muscles, and enhances flexibility.

As cherished members of our families, pet dogs bring joy, companionship, and unconditional love into our lives. Understanding their normal behavior is essential for building a strong bond and providing the care and support they need to thrive. Here’s a comprehensive guide to the typical behavior of pet dogs:

1. Social Behavior

• Dogs are social animals and thrive on companionship and interaction with humans and other animals. They often seek out attention, affection, and physical contact from their owners.

• Common social behaviors include wagging their tails, licking, leaning against their owners, and seeking proximity during rest or sleep.

The eyes and ears are not only vital sensory organs for your pet dog but also key indicators of their overall health and well-being. Proper care and management of these delicate areas are essential for preventing infections, maintaining comfort, and preserving your furry friend’s quality of life. Here’s a comprehensive guide to eye and ear care for pet dogs:

Eye Care

1. Regular Inspection

• Start by regularly inspecting your dog’s eyes for any signs of redness, swelling, discharge, or cloudiness. Clear, bright eyes indicate good health, while any changes may signal an underlying issue.

• Look out for excessive tearing, squinting, or rubbing of the eyes, as these may indicate irritation or injury.

A dog’s skin is not only their largest organ but also a vital indicator of their overall health and well-being. Proper skin care and management are essential for keeping your furry friend comfortable, happy, and healthy. Here’s a comprehensive guide to maintaining your pet dog’s skin:

1. Regular Grooming

• Use a grooming brush appropriate for your dog’s coat type and length. Long-haired breeds may require daily brushing, while short-haired breeds may need less frequent grooming.

2. Bathing Routine

• Bathing helps remove dirt, allergens, and bacteria from your dog’s skin and coat. However, over-bathing can strip away natural oils and lead to dryness and irritation.

• Use a mild, hypoallergenic dog shampoo specifically formulated for pets. Avoid using human shampoos, as they can be too harsh for your dog’s skin.

• Frequency of bathing depends on your dog’s breed, lifestyle, and skin condition. Generally, bathing once every 4-6 weeks is sufficient for most dogs.

Ensuring the health and well-being of your pet dog is a top priority for every responsible pet owner. Understanding common diseases that affect dogs and taking preventive measures can significantly improve their quality of life and longevity. Here’s an overview of some prevalent canine diseases and how to prevent them:

1. Parvovirus (Parvo)

• Parvovirus is a highly contagious viral disease that affects dogs, especially puppies.

• Symptoms include severe vomiting, diarrhea (often bloody), lethargy, and dehydration.

• Prevention: Vaccination is the most effective way to prevent parvovirus. Puppies should receive a series of vaccinations starting at 6-8 weeks of age, with boosters every few weeks until they are 16-20 weeks old.

As the temperature drops and snowflakes begin to fall, it’s essential to ensure that your beloved canine companion stays warm, healthy, and happy during the winter months. While winter brings its own set of challenges for pet owners, with some extra care and attention, you can make sure your pet thrives even in the coldest of seasons. Here are some essential tips for caring for and managing your pet dog during winter:

1. Provide Adequate Shelter: If your dog spends time outdoors, make sure they have a warm and dry shelter to retreat to when the weather gets harsh. Whether it’s a sturdy doghouse or a cozy insulated shelter, ensure it provides protection from wind, rain, snow, and low temperatures. Consider adding blankets or straw bedding for extra warmth.

2. Limit Outdoor Exposure: While dogs may enjoy playing in the snow, it’s crucial to limit their time outdoors during extreme cold weather. Frostbite and hypothermia are real dangers for dogs, especially those with short fur or small breeds. Keep outdoor activities short and supervise your dog closely to prevent any weather-related emergencies.

3. Protect Their Paws: Snow, ice, and road salt can be harsh on your dog’s paws, causing irritation, dryness, and even chemical burns. Invest in a pair of dog booties to protect their paws during walks or consider using paw balms to moisturize and create a protective barrier. After walks, wipe your dog’s paws with a warm, damp cloth to remove any salt or ice-melting chemicals.

As the chill of winter fades away, and nature begins to bloom, it’s time to embrace the joys of spring with your furry friend by your side. While spring brings about a sense of renewal and excitement, it also brings some unique challenges for pet owners. Here are some essential tips to ensure your pet dog stays happy, healthy, and safe during the spring season:

1. Regular Grooming Sessions: Springtime means shedding season for many dogs, as they lose their winter coats to make way for lighter ones. Regular grooming sessions, including brushing and bathing, can help reduce shedding and prevent matting. Additionally, grooming helps in checking for any ticks, fleas, or skin irritations that may arise as the weather warms up.

2. Watch Out for Allergies: Just like humans, dogs can suffer from seasonal allergies too. Keep an eye out for signs such as excessive scratching, licking, or sneezing. Consult your veterinarian if you suspect your dog is experiencing allergies, as they can recommend appropriate treatment options or medication.

3. Protect Against Fleas and Ticks: Springtime brings a surge in flea and tick activity. Ensure your dog is up to date on flea and tick prevention medications recommended by your veterinarian. Regularly inspect your pet for any signs of these pests, especially after outdoor activities in grassy or wooded areas.

4. Stay Hydrated: Warmer weather means increased activity levels for both you and your dog. Make sure your pet has access to clean and fresh water at all times, especially during outdoor excursions. Dehydration can be a serious concern, so carry water and a portable bowl when going for walks or hikes.

As the temperature rises during the summer months, it's crucial for pet owners to be vigilant about the well-being of their furry companions, especially dogs. As dogs are very much playful and active in nature, constant monitoring or observation is required to assess onset of heat stress as its onset is very quick and require immediate attention. Hence, knowing the sign and symptoms of heat stress will save the pets from ensuing negative impact on the health. Proper care and management are essential to ensure your pet stays healthy and happy during this adverse climatic condition.

Dogs release their body temperature through panting and by sweating through the nose and paw pads. If they can’t dissipate heat sufficiently their internal body temperature raises leading to hyperthermia (excess body temperature than normal, 101.0 to 102.50F).

Signs and symptoms of heat stress

The signs and symptoms vary as per the degree of stress incurred. At the initial stage of stress they show – increased thirst and panting.

Common Exotic and Indian Dog Breeds

India is home to a rich diversity of dog breeds both indigenous and exotic, each with unique traits suited to different environments and lifestyles. Among the exotic dog breeds that have gained popularity in India are the Labrador retriever, Golden Retriever, Beagle and German shepherd. These breeds often imported and are known for their friendly nature, intelligence and trainability. Labradors and Golden Retrievers are particularly famous for their loyalty and gentleness, making them excellent family pets. The Beagle, with its keen sense of smell and compact size, is a favourite among urban dwellers, while the German shepherd is valued for its protective instincts and versatility in roles like police work, guard duties and service tasks.

In contrast, Indian dog breeds, many of which are lesser-known globally, are uniquely adapted to the country's diverse climate and conditions. The Indian Pariah Dog is one of the oldest and most resilient breeds, found naturally across the country. Known for its strong immune system, minimal grooming needs and intelligence, the Indian Pariah is an exceptional companion that thrives with minimal human intervention. Another indigenous breed is the Rajapalayam, a sighthound from Tamil Nadu, historically used for hunting boar and protecting livestock. With its striking white coat and regal demeanour, the Rajapalayam is revered for its loyalty and bravery. The Mudhol Hound/ Caravan Hound, from the Deccan Plateau region (Andhra Pradesh, Karnataka, Maharashtra, Telangana and Tamil Nadu of India), is another notable Indian breed, known for its speed, agility and endurance, often used in hunting and guarding. Chippiparai, another hound from Tamil Nadu, has a sleek body designed for speed and was historically favoured by royalty for hunting small game. The Kanni, also native to Tamil Nadu, is a close relative of the Chippiparai and is recognized for its grace and loyalty, often kept as a companion dog.

Cannibalism

Cannibalism is a bad habit of birds in which the birds attack their fellow birds and eat their flesh. It is done through sharp end of beak, which causes deep wounds specially on vent. Sometimes the wounds are so deep that leads to death of affected bird. Two types of cannibalism vices are common i.e. vent pecking and feather pecking.

Cause / Predisposing Factors

• Over crowding

• Genetic predisposition

• Hemorrhage in external genitalia

• Protein deficiency (arginine and methionine deficiency)

• Loss of feathers • Wounds

• Prolapse of cloaca

Roundworms (Nematodes)

1. Ascaridia galli

A. galli is the common roundworm of poultry seen in intestines at the time of necropsy. This parasite may cause retardation of growth, loss of egg production, catarrhal enteritis and sometimes mortality due to obstruction of gut (Fig.9.1).

Etiology

• A. galli parasites are grey, thread like 5-10 cm in length.

• Eggs are elliptical with thick and shiny wall.

Pathogenesis

Transmission occurs through faecal - oral route. The eggs may survive for several months in litter and they take at least 10-15 days to develop the infective stage. The eggs of parasites hatch in proventriculus or intestine to develop fully grown parasite within 40-50 days.

Aspergillosis

Aspergillosis is a fungal disease of poultry caused by different species of Aspergillus sp and characterized by granulomatous nodules in lungs, thickening of air sacs and presence of fungal growth in lungs and air sacs in early age of chicks. It is also known as Brooders pneumonia (Fig.8.1).

Etiology

• Aspergillus fumigatus

• A. flavus

• A. nidulans

• A. glaucus

• A. niger

• A. candidus

Spirochetosis

Spirochetosis is caused by a spiral shaped organism Borrelia anserina and characterized by greenish diarrhoea, enlarged and mottled spleen, small necrotic patches on liver and linear haemorrhage in proventriculus. This disease is transmitted by a tick Argas persicus and thus also known as “tick fever” or “tick paralysis”.

Etiology

• Spirochete Borrelia anserina

• Spiral shape 8-24m long and 0.2 to 0.3 m wide microorganism having 8-11 spirals.

• Stained with aniline dyes

Chronic Respiratory Disease (CRD)

Chronic respiratory disease is caused by Mycoplasma gallisepticum and E.coli in birds under poor management and characterized by cloudy air sacs with thickening of their wall, accumulation of cheesy material in air sacs and lungs (Fig.6.1).

Etiology

• Mycoplasma gallisepticum

• E.coli

• Bad management like poor ventilation and inclement weather conditions

• Disease occurs more during winter and rainy season.

Ornithosis

Ornithosis is caused by Chlamydia and characterized by enlargement of liver and spleen, serofibrinous pericarditis, air sacculitis and enteritis. This is also known as chlamydiosis, psittacosis and is more common in parrots, pigeons and other psittacine birds.

Etiology

• Chlamydia psittaci group B

• Size 0.3 to 1.5 m

• Disease spreads from wild birds

Salmonellosis

Salmonellosis is caused by G-bacteria Salmonella and characterized by early chick mortality with necrosis and hemorrhage in liver, heart and spleen and enlarged bronze coloured liver with focal or diffuse necrosis, marbled spleen and/or oophoritis and salpingitis in adults (Fig.4.1).

Etiology

• Salmonella enteritidis var. Galinarum (S. Galinarum).

• G-, rod, non lactose fermenter.

• White small colonies on MLA and pink on BGA.

Ranikhet Disease

Ranikhet disease is a contagious viral disease of poultry characterized by high mortality petechial hemorrhage in proventriculus, ulcers and hemorrhage at caecal tonsils and pneumoencephalitis. It is also known as Newcastle disease (Fig.3.1).

Etiology

• Paramyxo virus

• RNA virus-3 types

• Lentogenic- mild virulent

• Mesogenic- moderate virulent

• Velogenic- highly virulent

Pathology of nutritional deficiency diseases are described in chapter etiology of this book. However, specific deficiency of nutrition that leads to development of clinical signs and lesions in poultry are summarized as under (Fig.2.1 & Fig.2.2):

Vitamin Deficiency

1. Hypovitaminosis A

• Vitamin A is considered infection resisting vitamin because it facilitates the proper development of bursa, immunity and epithelium on mucosal and skin surfaces.

• Deficiency of vitamin A leads to swollen glands in oesophagus i.e. nutritional roup.

• Avian Inflammation

Inflammation is a process which begins following a sublethal injury to tissue and ends with complete healing or death. It is characterized by five cardinal signs. Cardinal signs of inflammation are:

• Redness

• Heat

• Swelling

• Pain

• Loss of function

• Inflammation is beneficial in most of cases expect

• In prolonged or unending process

• In inflammation of immunological origin i.e. hypersensitivity and autoimmunity.

• It provides basic foundation of pathogenesis and pathology.

• It is now said that immunity is the resistance of body, while inflammation is the process by which the immune mechanism are implemented.

• The basis of inflammation remains same be it mammal or birds. For details, one can refer the chapter inflammation and heading in book “Illustrated Veterinary Pathology”. However, there are some differences in reaction in birds which are briefly listed below:
