hmmmm..in some cases she sounds real concerned, the whole kill factory bit, making sense since their mutts, but it could be a cover.
she kinda seems like shes trying to hard to please making the dog seem perfect and stick out. different colour eyes from others, micro chipped(which she probably think all owners would like because it is expensive), little then all the others. did she know you wanted a small dog before hand, because if so it would seem a bit fishy, because how shes making it seem so perfect. Is she close by is there a way you could visit it first.
I must admit i got my dog off the internet. I took a very dangerous chance. Though i knew it was a pup watched it grow background seemed to be a home,took a chance beleived her story that another dog vcame over or something and impregnated her dog, and i took a very risky chance, luckily i was lucky she met us half way. i got the pup, and through vet checks found out he was healthy. It wasnt till after i found out back yard breeders can produce unhealthy dogs, becaause they are not real breeders, and there are scammers.
What also made me beleive the lady that poe was a mistake dog and desperatley needed a HOME. was that she was upfront honest. No she hadn't taken him to the vet, he hadn't had his shots, she could have lied for all i know, i didnt know where she lived.
So hopefully about all the things she has done for it(microchip, deworm, shots, de-fleed) is true, and also all his rare qualities that would seem to please owners is true (smallest, different colour eyes)
All i am saying is make sure to the best of your ability she is not putting you on, for on this forum i have also heard alot of sad cases where people were waiting for a dog that never came, or when they got it they didnt know they would be paying for a 10,000$ hip repplacement or heart surgery.
Just be careful. He is beautiful, the terrier mix!
