Your Pet's Reproductive System

Animal Theriogenologist also known as Animal Reproductive Specialist today go out and teach animal lovers, owners and rescue group organizations about the world of Pet Reproductive Health. A common question that is asked is "Does spaying or neutering pets really calm them down?" Spaying and neutering aren't a cure all for aggression, but they can cut back on undesirable behaviors like mounting, territory defending, fighting and irritability caused by hormones.

 Spay and neutering pet can cause animals to gain weight, but with a healthy diet and exercise can help level out and provide health benefits.

Reproductive health problems such as uterine and prostate infections, breast, over and testicular cancers can also help with some medical problems.  In females particularly, spayed females also avoid the discomfort of going into heat as well as the health risks and expenses of pregnancy and giving birth.

Pets that become altered have also been known to wander around less often because they're not off searching for a potential mate or fighting. Neutered males are less likely to spray urine around the home or mark territory.

Just like humans sexual maturity for fertile animals varies from pet to pet. Male puppies can produce sperm when they are around 5 months where females begin around 6 months. Smaller breeds often have their first cycle earlier than larger. In addition, cats can start reproducing between 4 to 6 months depending on the breed.  Smaller female dogs cycle up to 4 times in a year and larger breeds cycle every year and a half. Each cycle lasts 2 or 3 weeks and brings light discharge resembling a period. Cats can have numerous cycles which until pregnancy in a year. Typically, every few weeks during the spring and summer. These cycles are linked to diurnal rhythms or daylight exposure, but indoor-cats only cycle year round thanks to artificial sunlight exposure. Cats only ovulate, through after mating and their bleeding generally isn't noticeable. Pets are most likely to get pregnant in the first couple of weeks after the bleeding stops.

Pets can be infertile based on genetics, illness, infection, environment and certain behaviors can all cause infertility. Pets don't go through menopause, they usually don't keep the same level of fertility as they age, older unspayed female pets can still become pregnant. If they aren't spayed and exposed to fluctuating levels of reproductive hormones related to their heat cycle. Regardless if they're pregnant or not.
