Why is my dog suddenly food aggressive and food obsessed?

Updated On September 23rd, 2025

Pet's info: Dog | Cane Corso | Male | neutered | 6 years and 3 months old | 110 lbs

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.
