I have a client whose dog came in about two years ago. I had her for 10 months in which we got a jr title then a sr title on her. She then went home, hunted for duck season last year and has started hunting this year. She had come into heat once before she came to me then never while she was with me. Since she has been home, just over a year, she has not come into heat. The doc says it is a product of going into training for so long at 6 months of age and she may or may not ever come into heat now. My question is, is there anything that he can do to help her start her heat cycle?
