Cozy went into heat at 7 months. It was three weeks from hell. She was miserable had to be separated from her best friend the 120lb golden b/c he was unneutered at the time. He has since been neutered. The two of them were pitiful. He would not eat. All he did was cry.
The sad part is I had an appt. for her to get spayed but had to cancel it. My vet does not operate on small dogs in heat.
