Q. My dog is 13 months old and hasn't gone into heat yet. Do you know why she hasn't?
My golden retriever is 13 months and hasn't gone into heat. I plan to breed her, as she is an AKC show dog. Thank you for your help. I don't know why she hasn't yet.

A. It's not that unusual for larger breeds to go into season at a later age than small breeds. I had a Doberman female years ago that had her first heat around 16 months old.

It would probably be a good idea to have a blood panel for thyroid function run, as a baseline to refer to in the future. I do this with all my breeding dogs.

If you have concerns for her health, I'd seek the help of a qualified reproduction vet. Good luck.

Puppy Tube Feeding Kit

Feeding tube is 16 inches long (41cm) and approximately 3/32 inches (2.7mm) outside diameter. It is best to store your feeding tube and syringe at normal room temperature. In colder temperatures the feeding tube will become rigid and stiff. At body temperature, the tube becomes softer, resilient, and completely flexible. Syringe is 35cc and attaches to the integral funnel end of the feeding tube. The opposite end of the feeding tube has a closed rounded tip with 2 side port 'eyes'.
