Someone gave me some cooked bones. Nice large bones. I gave one to my 7 1/2 year old blk male and one to my 7 month old puppy. This was in the evening in her kennel. I was only going to let her have it for an hour or so when I went in to retrieve the bone it was gone she had eaten it all. The next morning was a disaster. The poor little girl had serious diarreah. It cleared up by the next evening and she seems to be fine now. But I learned a lesson unfortunately at Zoey's expense.
based on my experience I would NOT feed bones to any dog under 1 yr old.
Cooked bones are a no-no anyway, because they can be brittle.
Actually the problem isn't the age the dog gets a bone to chew on, but if it ate everything, marrow included, it was most likely too rich for her system. I let my babies have raw marrow bones (with most of the marrow removed) until they were used to eating the bones. They have been getting them since about 4 months of age.
The bones were cooked in meat not just boiled bones. I thought since my older dog didn't have any problem that it must have been that she was so young. My Bad Just ignorance on my part. I will be careful in the future. Yeah I am sure that it was the rich marrow part that caused the problem.
I wouldn't use marrow bones in any form as dogs often break teeth on them.
I use fully consumable RMBs (mostly from poultry) or bully sticks.
