I noticed everyday that Mama dog is getting SKINNIER AND SKINNIER and at the point right now, she is on the edge of being BONE AND SKIN. I have no idea why! She is fed double then she was before. I changed her feed to SCIENCE DIET based on Vet's order, once the puppies were born. I give her the Science Diet 2x a day and I have a bowl that is "BOTTOM LESS" of our regular feed. I have seen her eat just fine but she is NOT gaining weight at all. Anyone have any ideas why? ANOTHER QUESTION: Kind of a lil "ADULT ONLY" type of question, not sure. When the mom is outside, the pups since to rather sleep or suck on each other's private areas. I have NEVER seen that before and it kinda disguests me (Im preggo so It's hard to watch stuff like that!).They are well fed, nursed with mom as well as taking the bottle from me, when needed (8 puppies won't all fit around mom for feed, they end up pushing off and such, she is a small mama for 8 BIG puppies). 1 expecially does this, MAX, the BIG BIG BIG boy. Everytime I see him do that, I pick him up, tap his nose (Their eyes are open and they are very active now, Im sure it's a good time to start training some stuff with them) and move him to a different spot but he just goes to another pup and search for their "PEE PEE" to suck on (NASTY!) Is this normal? GROSS!
