HelloCustomerand welcome to Just Answer,
Thanks for your question concerning Roxy. My dog gets extra food from my children also.
To answer your question, the grape jelly should not cause any problems. Its more of a concern if they are eating real grapes. My lab has got plenty of PB & J's over the years and never had a problem.
If you notice that Roxy develops any vomiting or diarrhea, then I would certainly contact your regular veterinarian, but again, I doubt you will see any problems.
Thanks and let me know if you have any additional questions!
We just had a horrible scare a couple of years ago with her liver and I just wanted to be on the safe side. My son will drop real grapes on the ground and she won't even touch them. But when it comes to the jelly she is all over it!!
Yep, you should be fine....but again, if you notice any vomiting or diarrhea, then contact your veterinarian.
