I had a cousin that had bought a dog from a breeder, it was a small poodle. My cousin already has a shitzu. She had the poodle puppy for like 3-4 months or more. The two dogs were just starting to get used to each other, and my cousin was having some problems with the training.
I forget if it was house breaking it or what, but the usual stuff that is not that hard to deal with, not real issues with it's temperment or behavioral problems.
But just cause she hit this rough patch with the puppy she called the woman she bought it from and asked if she would take it back!
I was glad she did that and didn't just turn it over to the humane society, but still. The poor thing had gotten used to it's surroundings, my cousins other dog was enjoying the company...
Sorry, just saying that you could reminded me of that.
Can't wait to hear how it goes and see some pics.
