Red Blood Cells of Dogs

The main function of red blood cells (also called erythrocytes) is to carry oxygen to the tissues, where it is required for cellular metabolism. Oxygen molecules attach themselves to carrier molecules, called hemoglobin, which are the iron-containing proteins in red blood cells that give the cells their red color. Oxygen is carried from the lungs and delivered to all body tissues by the hemoglobin

Behavior Problems Associated with Aggression The most common behavior problems in dogs are those associated with aggression. Most cases involve a dog’s attempt to distance itself from the situation. There are many types of aggressive behaviors with different motivations, but fear, anxiety, uncertainty (conflict), inheritance (genetics), and previous lear

Dogs are highly social animals and are well adapted to living in groups. Studies have also shown that they are very good at interpreting human gestures and behavior. Dogs interact with each other and people through body postures, facial expressions, tail and ear positions, raising of hair or “hackles,” vocalizations, and scents. Although dogs evolved from the grey wolf 12,000-14,000 yea

The techniques used most commonly to modify dog behavior include habituation, extinction, desensitization, counterconditioning, response substitution, and shaping. A behavior modification technique called flooding, described below, is not used very often because it is more likely to make animals worse. While it is claimed that punishment is frequently used with varying degrees of success, few people us

Many “health” problems faced by pet dogs are associated with behavior problems or unmet expectations about the pet’s behavior. Your veterinarian will first need to rule out any possible health problems that could be causing your pet’s behavior to change. For example, a medical condition could be causing your pet to urinate in the house. Your veterinarian will take a behavioral history before

Behavioral medicine is the scientific study of everything animals do, whether the animals are insects, birds, mammals, fish, or people. The field of animal behavior is concerned with understanding the causes, functions, development, and evolution of behavior. Behavior refers to the actions or reactions of an organism. Behavior is usually in relation to the environment, and is controlled by the endo

Puppies can generally be taken from their mother and littermates beginning at 7 to 8 weeks of age. Puppies, like babies, require a lot of attention, including veterinary care, feeding, socialization, and training.

The reproductive cycle in female dogs has 4 phases. Female dogs that have not been spayed (bitches) typically have 2 estrus or “heat” periods per year (about 6 months apart), each lasting about 2 to 3 weeks. In some dogs, the intervals between estrus are much longer. The first heat occurs between 6 and 15 months of age, depending on the size of the dog (later in larger breeds). Females can become pregn

In addition to feeding and exercising your dog, other aspects of general care are needed to keep your dog healthy throughout its life. These include routine veterinary care for vaccinations, parasite control, and dental care; grooming; and protection from household hazards.

Pet ownership carries responsibilities that should not be taken lightly. Pets are family members that need to be cared for throughout their entire lives, not disposable possessions that can be discarded if they become inconvenient. Pets also carry financial responsibilities for housing, a quality diet, and veterinary care. The latter includes routine veterinary examinations, preventive vaccinations,
