Thank you to everyone for your comments. I really hope she does think about what I said and reconsider breeding her. I just feel really bad for the poor little poodle. And to tell the truth the "you're not a vet" comment hurt my feelings. I can't tell you how often I get phone calls from customers for "vet" type advice.(I always remind these people that I am not a vet,BUT this is what I would do) Or how many times I have spotted problems that needed to be checked and told the owners they needed to make a vet appt. I actually had a customer tell me one time that she thought her dog may be about 3 weeks pregnant(her daughters dog had been visiting), so I very gently palpatated, felt puppies and sent her to the vet. The vet says no puppies, she's not pregnant........6 weeks later she delivers 4 cavalier king charles/yorkie mix pups. That customer still brings her dog and the puppy she kept to me. She uses a different vet now

. Thanks again to everyone. And if that is how little that customer thinks of me, then I really don't mind loosing her business.
ps. the cavalier/yorkie puppy is one of the cutest puppies I have ever seen!!!
