I worked at a Petland. Worst experience of my life... Really opened my eyes to the horrors of pet stores. I bought my rabbit from a Petland, but that was kinda a rescue...
What about Petco? How are they for animal treatment? I ask because my sister in law buys all her pets from there.. (including the guinea pig that we adopted from her ) They -seem- to be pretty caring about the animals, but how can you ever be sure?
It is not only major chain pet stores it is also you local pet store or I should really say puppy store.It's not just petland, it's almost every if not every major chain pet store that sells puppies. Reputable breeders don't have litters often enough to supply their demand. Not only that, reputable breeders screen potential buyers and they can't do that if they're going through a pet store.
I know that it's not just chain stores, I think OP just asked about chain stores though. And really you're best bet is going through a reputable breeder or a shelter/rescue.It is not only major chain pet stores it is also you local pet store or I should really say puppy store.

This place has a local cable TV commercial that in there ad says new puppys arriving weekly. Now if you Google "American Puppy Club NJ" you will come up with a lot of links with complaints. The following link is just a small sample.
