Basset puppy attacking kids

This is Homer. We brought him home from his breeder in July at 8weeks old. We specifically chose a basset because everything I’ve read they are loving and good with kids. We have a lot of kids including toddlers but are not new to dogs. But this dog has me losing my mind. He is VERY aggressive towards my kids. They are all very respectful and loving towards him. I don’t let them pull on him or do anything unkind. It’s mostly about food. If there is food anywhere he will attack my toddlers. If one of my older kids tries to move him(today my 10yr old tried pulling him out of the pantry by his collar) he will attack them. He breaks skin. It’s insane to me coming from such a young dog of a gentle breed.

I do not want to get rid of him. We love him. Even though he’s a fucking asshole. Right now we kennel or put him outside if anyone is eating. But it’s hard to avoid every situation. My 2yr old got bit hard in the arm today because she was playing in the backyard and walked by someone Homer wanted.

Is this normal? Was I just wildly uninformed? We’ve had a pit bull, labs, another hound, currently a chihuahua, and never have they been like this!
