I'm not sure if Cash is just getting crankier in his old age or what is going on. Last night after dinner, I was in the kitchen putting the dishes in the dishwasher and the DH was in the breakfast room with the dogs. Suddenly, there was growling and snapping going on in the breakfast room. Cash and Scooter were going at it over a plate that the DH had put down for them to lick. Cash has never liked Scooter and Scooter has always pushed things but this was the worst Cash has ever done. Usually it's just some warning growls and lip curls, but this time it was more snapping and teeth. And Cash wouldn't let it go! Little snot! I finally walked over to him and got between them. I pointed at Cash and said "Let it go now, dude!" and he backed off. But, geez, he's 15 years old and weighs 17 lbs and Scooter is 10 and weighs 38 lbs. Those aren't good odds for the little guy.
I can tell I'm going to have to watch Cash closer in the future. He's always been really bad about being snarky and growly, but this was way over the top. I don't want my little man to get himself hurt. I guess since he's senior dog, he thinks he can do what he wants.
