I dont know much about show dogs but if someone is willing to show a dog in the first place then change her mind about it then Im sure it was a good reason, Also I know if I found out someone was ranting about me online to people about the decisions on MY dog I really wouldnt be happy and I'm sure she wouldnt be either, Maybe actually talk to her about it instead of coming on here and talking about her like shes has made the wrong decision as someone has already said you dont own the dog, you Co own it so am I right in thinking the dog is with her all the time? as in her care? does she pay the vet bills? so what she does with it is completely up to her even if she did make a verbal agreement I'm sure she had a good enough reason and I'm sure she was thinking of the dogs health more than your wants of a show dog just like any other loving owner would do. You should try looking at it from her point of view I actually think she has made a very wise decision to get her spayed especially if there are many male dogs about I think I would prefer a spayed dog rather than having puppies running around.
