If my dog went through a false pregnancy after her first heat. well this cause her 2nd heat to be off track?

We have a lab which she is in training to be a service dog. Our trainer decided that she would like to breed her this one time and save 2 females from the litter, than spay the mother. She has already gone through her first heat, and should be coming up on her second heat. But shortly after she went through the first heat she went through a false pregnancy. Will this cause her 2nd heat to be late, or have complications when ever we do breed her? Do you think that it is a good idea to breed her after she has gone through a false pregnancy?If my dog went through a false pregnancy after her first heat. well this cause her 2nd heat to be off track?
The dog is in training to be a service dog and the trainer wants to breed her? I question the professional ethics of this trainer.If my dog went through a false pregnancy after her first heat. well this cause her 2nd heat to be off track?
I once heard of a connection between false pregnancies and uterus cancer/tumors,I would recommend not breeding her because of the chance that she could pass this on her her female pups,unless you assure that she and all the females are definitely spayed,thus not carrying on the gene,and not having a uterus to get a tumor of cancer...
If she has already had a false pregnancy then yes, it would be very dangerous to breed her. She could have serious complications. Obviously there is something wrong with her hormone levels. Get her spayed to keep her healthy and alive.
False pregnancy carries with it a much higher rate of pyometra, and you shouldn't even think of allowing her to breed. The faster you spay her, the better.
honey all dogs do a false pregnancy to one extent or another. but yes one who does it to the full degree is more prone to pyo and will usually do a false every heat and breeding them makes it WORSE the next time around.
