Need a like button for Ruth. LOL. I agree, the guy seems a bit suspicious only because of the age of the pup, how long he has had it and now he has to move. Seems suspect but then, what do I know. Flipping is a problem because of several reasons:
1. The dogs are often mistreated by the flipper. They are kept in small cages, dirty places, sit in feces, and a wide range of other deplorable situations. Mind you, there is always an exception to the rule.
2. Dogs that should be put down are often rescued. It doesn't matter what the temperament is, just the breed and the looks. The dog could have serious aggression problems but they don't care, health problems, etc.
3. They lie outright to the people adopting the dogs. Tell them different stories about the dog, lie about getting them their health checks, lie about temperament. One person on here rescued a dog from a flipper, told how loving he was, etc, etc, the dog attacked her and broke the skin on her arm. Imagine if it had been a family with kids who adopted that dog. Sadly, the dog had to be put down due to aggression. Another person paid extra because the dog was spayed, got the dog and surprise, she went into heat. So yeah, some lies can be small, some big.
4. The dogs are there for a profit. You lower your profit margin if you provide the proper food, vet care, socialization and training. My friend went to buy a French Bulldog and when she got to this dirty house, the guy walked into the backroom and brought her out. Behind him, she caught a glimpse of puppies in cages stacked three high. No adult dogs were present, just the puppies. Turns out, after some research, the guy was a puppy broker. He would collect puppies from people new to breeding, byb's or puppy mills and then resell them at a higher price. The puppies he didn't sell disappeared and the ones that did had a lot of health problems (my friend didn't think about anything but saving that puppy so she brought her home, she had a serious infection that almost cost the puppy her life and it cost my friend nearly 2k in vet bills after all was said and done).
So that is why we feel flipping is wrong. If the guy isn't flipping then all the best to him, if he is, then I hope he doesn't make a dime but the puppy gets rehomed. Sadly, if he makes money off of flipping, he will keep doing it.
