Although fertility issues can arise in dogs of all ages, older dogs tend to be the most common culprits. The reasons for fertility issues can be varied and differ from one breed of dog to another. For instance, uterine cysts are common among dogs above the age of 6 years and can lead to infertility in female dogs.

Pre-existing Conditions can affect pregnancy

Factors such as pre-existing medical conditions, especially uterine infections that affect implantation usually lead to infertility. For most dogs, fertility issues are caused by insemination or breeding during the inappropriate time in the female’s oestrous cycle. In simpler terms, breeding when the female dog is not fully in heat. This makes it important to monitor the heat cycle of a female dog and allowing for mating only when she is most fertile.

At Smart K9 Fertility Clinic, the dog reproductive team keeps track of your bitch to ensure breeding is performed at the most appropriate time.
