I have never heard of Weetabix . I wasn't sure if you were saying yor friend brought them for Sam ( and they were a dog type treat) or if she brought them for you ( a human treat
)
If it's for you , I wouldn't give them to Sam because of the Chocolate which is toxic to dogs. If they are a dog treat then I would hope the chocolate was just a 'flavoring' that was O.K. for dogs and not real chocolate.
The only human treat type foods mine get are raw carrots ,chicken , and sometimes yogurt and apples. I haven't tried much else because I wasn't sure for a long time what was O.K. for them to have. I know Green beans are O.K. but I think the frozen ( thawed ) non cooked kind are best.
