Factors Affecting Reproductive Performance
Researchers were interested in studying reproductive success in female dogs (bitches) after artificial insemination (AI). Artificial insemination refers to the deliberate introduction of semen into a female by a veterinarian. No natural breedings were included in this study.
Caloric requirement for pregnant and nursing dogs
A lot of breeders don’t understand the caloric requirements of a nursing mom. During the last trimester of pregnancy, her caloric needs are two to three times her normal caloric needs. During nursing her caloric needs can be as much as six times her normal caloric needs, depending on her litter size and metabolism. This will get a little math-y and just a little technical. I think it’s better if we can understand a little of the why before we learn the how.
The importance of a reproductive veterinarian and how to choose one
Breeding successfully requires several important partnerships, and our veterinary partners are critical. Most pet owners have a general practice vet they use, and may see a specialist such as an orthopedist or a cardiologist. For a breeder, one of your most important veterinary specialist partners is your reproductive vet.
What’s so important about dog DNA?
This blog post will cover why it's so important to purchase a puppy from a breeder who does DNA tests on their breeding stock and what to look for when provided a copy. We will cover in a future post why you might consider DNA testing your own dog, especially if you rescued, purchased from a puppy store, or bought a puppy without researching the breeder.
The Impact of Inbreeding on Litter Size
Inbreeding refers to the breeding of related individuals. Inbreeding depression is the reduced biological fitness (an animal’s ability to survive and reproduce) in a population because of inbreeding. For example, scientists researching the Australian Thoroughbred horse population found that inbreeding led to reduced racing performance.
Common weaning mistakes
Weaning puppies successfully is as much art as it is science. Weaning is a critical time for puppies and impacts their survival, their physical development, their behavioral development, and their cognitive development. Here are a few common weaning mistakes I hope you avoid.
How often to breed and when to start breeding
Back in the day, best practice for breeding was to wait until a dog was at least 2 - 4 years old, had at least 3 heat cycles to breed, and also to skip at least 1 cycle between litters. Like many other things we used to do, when science is finally applied to our profession and we get information from good data, we realize that we could be doing better.
Effects of Diet Restriction on Lifespan
Obesity is the most common preventable disease in dogs in North America. Approximately 25 – 30% of the general dog population is obese and nearly 50% of dogs over the age of 5 are overweight.
Associations Between Sterilization Status and Lifespan & Cause of Death
Lifespan in the outcome of the differential risks of a myriad of possible causes of death. While life history theory suggests that reproduction carries a potential survival cost, we actually know little about how reproductive capability affects lifespan and the risk of dying of specific causes of death. Because elective sterilization (spay-neuter) surgery is commonly performed in pet dogs, they provide an excellent model to investigate this topic. The authors studied the effect of surgical sterilization on lifespan and cause of death in a large sample of domestic dogs. They controlled for age in their analyses, which is important, because a longer lifespan might lead to a higher risk of dying of diseases that strike at a later age.
