Let me start off by saying that Snickers is my first dog, so, naturally he's my first old dog. He'll be 10 this December and his behavior seems to have changed some and I'm not sure what to make of it. He's always been a bit of a pig when it comes to food, but its gotten much worse lately. In February I got sick and was in the hospital and just recently got to come home and I don't know if some of the stress from that could be causing this or what. He constantly acts like he's starving. He roots around all over the house for food all the time and inhales his food then runs to try and steal Ava's. We've gotten to the point where we feed him in one room and Ava in the other, but when you put food in his bowl, he's eaten all of it and is next to you begging for more before you can walk the 10 feet to Ava's bowl. There's so many other examples too...its really frustrating. I'm not sure if its a training issue or something where he's just getting older and changing. He's been checked at the vet for it several times as its been progressively getting worse and, aside from being overweight (go figure ) he's in great shape. I'm doing all that I can to curb him from being so obsessive - Ava's bowl is in her crate now, he gets dinner from a Kong that he has to work at, and I spend a lot of time just supervising so he doesn't get into stuff. I've even resorted to using a squirt bottle (just like with a cat) because he seems to have realized that I can't walk too well anymore and won't listen to any of my commands to "leave it" if I'm more than a few feet away from him. Are behavior changes like this normal-ish with him getting older? And, does anyone have any other suggestions on how to stop the obsession?
