Why is my dog suddenly food aggressive and food obsessed?

My 6yr old Cane Corso has become severely food obsessive. Like he can never have enough food and is now going after our little dog if she's even near food that we have. He steals off the counters and he never used to do this. I'm concerned for my kids at this point when these fights break out. What could cause this type of sudden onset obsession/aggression?

I would recommend taking your dog to the vet for an exam, as there are definitely some medical conditions that can cause a dramatic increase in appetite like this. Some possibilities would include Cushing's disease, diabetes, a thyroid tumor, or a problem with absorbing nutrients from the GI tract. Your veterinarian can do blood work or other testing if needed to help determine what may be causing this.

I recommend to have him checked for endocrine diseases such as hypothyroidism and Cushings disease. This could be the first indication that a problem is developing. Also have him checked for parasites. I hope this helps.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Buddy! I worry about sudden behavioral changes in older dogs. I think it is best to have him seen by your Vet to rule out medical causes for his behavioral changes (pain, arthritis, decreased vision). The increased appetite absolutely could be medical in nature and something to focus on. I would have an exam done and full senior blood work to rule out diabetes, over active thyroid, Cushings, etc for the extreme hunger. The Vet can see if he is painful. I hope this helps and I wish you and Buddy the best!
