My mom said my aunt got a new miniature pinscher puppy (probably from a byb) but she feeds him only canned dog food? (mighty dog) This can't be good for him right? Don't dogs need dry food for their teeth. And don't puppies need puppy food? This is the same aunt that tried to talk me into giving her Lucy when she came over one time. She even got mad at me and cried when I said no. I feel bad for the poor little guy. She also has two other dogs who are fed crap food but it's dry food and not canned. A 12 year old pomeranian and a 1 year old mutt who lives outside as the "yard dog". If I try to recommend foods she gets very angry with me so I have given up.
