Yes, I understand the concept, but the breeder and I can't imagine how it could have happened. Their property is essentially sealed. The dogs' kennels have concrete walls with fencing on the back, top, and front. The only breed on the property are Dobermans and their yard is totally fenced.
If she is a mixed breed, her daddy was one athletic/brilliant dog.
I scanned her pedigree from the AKC. http://www.flickr.com/photos/bekabug/1252960787/
When I talked to the breeder she said that the sire's DNA is on file with the AKC and we're welcome to have her tested. My husband and I are trying to decide on if checking his DNA against Coco's is enough, or if we want to do an independent test on all three of them.
We found these little kits where you swab cheek cells from the dogs and send them off and you get a nice little parentage report. It's $38 per test. I'm curious to know what's going on with Coco, but not sure how curious.
We had a heated exchange recently with our vet over heartworm pills and Coco's parentage. They wouldn't give me a prescription for a generic pill because it had ivermectin (I think thats how you spell it) and if she had any collie/herding dog in her, she'd die.
Well, I did a little of my own research and the consensus is that there isn't a high enough dose in heartworm pills to bother ivermectin sensitive dogs. It is really only a concern when treating mites or the mange. I brought this up with the Dr and was told that may be so, but they still couldn't give me a prescription to an online pharmacy because they didn't have any prescription pads to write the script on.
Very educational. Also, time for a new vet.
