Like humans, dogs can have problems to become pregnant and conceive and produce puppies. Since their reproductive system and their reproductive life is shorter than humans, it makes it more imperative to address the cause of the problem. At QCAH we perform blood tests, ultrasound, artificial insemination (trans-vaginal and surgical), ovulation timing test, frozen semen surgical insemination and soon we will have available the TCI (trans-cervical insemination, etc. Dr. Mendez has special interest in Canine Reproduction and he attended several courses and hands-on labs. in the US and several other countries. He has experience working with English Bulldogs and French Bulldogs breeds known to be difficult to reproduce.
