Well maybe what he is getting at is shelter dogs typically are mutts which are more likely to be much smarter than your pure-bred anything due to inbreeding. Mutts also live much longer and healthier lives, which is nice.
- Never buy an animal from a pet shop; they come from mills which is bad news (pretty obvious, rite?)
- It is best not to buy from a breeder either, imo. Breeders are not helping the homeless animal population with their shallow business. Very few breeders out there actually care and will spay or neuter the animal before taking payment.
Yeah I would never buy an animal from a pet store. Ever. I learned that as a kid. Shelter/rescue looks like the way to go.
Lots of good info in this thread. I have a lot to read and think about after I get home from work.
