No offense to the OP but this is why you should always meet the dog before taking on the challenge. Because, if you don't meet the dog and just have him shipped to you... you don't know what you're in for.
I don't think those are the same dogs. I've heard of a yorkies coat changing with growth... but not
that much. The one coat is darker than the other. Now, different foods can cause the coat to be shinier or duller... which many posters failed to mention (dogs aren't born with shiny coats, after all
)... but, that's just too much. Those can't be the same dogs. They look nothing alike to me.
In this case, I feel sorry for the OP and the yorkie. I don't know who to feel more sorry for, though. The OP was obviously scammed. Rather intentionally or not. She was. But, the yorkie is obviously
very stressed. And, shipping her back and forth is
not going to help with her aggression. If anything, it's going to make it worse because she's stressed.
I swear, if I had the extra money and one less dog than I have.. I'd offer to take this baby. She's very pretty (I think) and I have the patience to handle an aggressive dog and rehabilitate her. I also don't have any kids- so, kid aggression wouldn't be a problem for me.
