I have another question regarding heat - so the length of proestrus is 15.7 +- 1.6 days in wolves, which means individual proestrus can be 21 days long in wolves. In wolfdogs this seems to be even longer - Frei is now 28 days in heat and still not flagging completely (she insists on at least 10 minutes of play before being willing to stand still for some smelling and licking). Of course she was not bleeding continually since the beginning, but now she is bleeding profusely for a week, but shows no signs of discomfort except frequent licking. Male dogs thought she was smelling really nice since the beginning, but a week ago they started to be very very insistent on continuing their walks in our direction.
Wolfdog breeders seem to think it is normal to have such a long heat in wolfdog (also the vet who is doing progesterone tests), but my regular veterinarian is concerned about development of cystic endometrial hyperplasia due to long heat. He says that a bitch should not be in heat longer than 4 weeks.
So any vets here (I know about Ina but there may be more?) - what is your opinion? Should I be concerned? Should I let him stop her cycle, if this continues and if, then when?
