The head just looks sooo big compared to the very short legs. I have not seen that before, personally.
I believe you said you werent going through with buying him. I applaud that decision.
I recently was in a pet shop (against my better judgement) and right off fell in LOVE with a little tiny chiauhau. I visited him several times and I could just tell he was ill, but the pet store kept lying. Sure enough, they had to seperate him from the other puppies because he was ill. The puppy was very shy at first, but he started recognizing me and one time when I went to check on him he totally kissed me (out of nowhere). There was another time where the employee had the dog and it jumped out his hands at me, thank god I caught him!
Anyway, it BROKE my heart, but I knew I could not have him and as much as I wanted him I just had to stop going. The last puppy I got from a breeder ended up being very ill and having problems and I could just not put myself through that again.
I will never let myself go into another pet shop. I know they dont come from good breeders and it just ends up in heartbreak.
