We have just given our puppy, Lilu, a primal 2in raw beef marrow bone. She seemed to be confused about it at first and started rolling around it a lot (she was in her crate with it), and jumping around. I then held it for her and she started trying to take out the marrow. A couple minutes later she began to throw up. She threw up a total of 3 times but it was all food (no bile). She ate about 45min-1hr before she started throwing up. We took the bone away from her because we don't know if thats what caused it. Has this happened to anyone? The guy at the local pet store told us she can have these bones even though she's only 11 weeks. Any opinions anyone?

It's not uncommon for marrow to be too rich for some dogs especially if they've never had it before.

Next time I would give that on an empty stomach rather than combined shortly after a meal. I don't think there's anything wrong with the marrow bone regardless of your pups age. I would however take the bone away after eating due to the bone being rather hard and can chip (adult) teeth.

I thought dogs are aloud to have raw bones. I know they can have raw chicken bones. Are these bones (beef) to hard for them? If so do you know which bones they are aloud to consume?

Usually, any bone that is a "weight bearing" bone from red meat sources shouldn't be given to dogs. Think leg bones etc. However, other bones (rib, tail), white meat (Chicken, Turkey), Rabbit, Fish bones are all okay. The marrow bones are traditionally the leg bones.
