I've only rescued dogs. Took my neighbors cause he locked him up for 3 weeks when he went on vacation to Florida, put water and food in those 5gallon construction spackle buckets! Water was infested with mosquitos and food had ants, flies and maggots all in it! Cut the bars on the guys porch and took the dog!
The dog I have now, got her from a no kill shelter. She's cute, will post pictures when I get home, but the guy that had her before me used to put cigarettes out on her snout.
I like rescuing better than breeders. I know a lot of people that have had issues with breeder dogs.
