I work for a pet product distributor. I'm in pet stores all day. Today, while I was reseting an aisle for one of my "closer to home" clients. I saw 3, very young, too young, chihuahua puppies come into the store. I was there 3 hours and saw this.
My assumption is a breeder "released" her puppies today. My, they looked too young. They were making puppy crying noises. 2 of the 3 brought the pup in, in a blanket, the other dumb @ss brought his pup in naked. Like a really young, really tiny puppy should be naked like that in 15 degree weather.
Anyways, it is a law in my state that puppies cannot be sold before 8 weeks, but somehow a few are slipping through the cracks. I've seen 4 week old pits, lots and lots of 5 week old shelties (I've seen the 5 week old shelties at different time of the year, but have continued to see them for 3 years now, so I assume it's some dumb breeder), and now, I'm guessing, 5 week old chihuahuas.
