Marley has been acting like a total butt the last few days. I was out with them yesterday and Dosia was playing with the cat and Marley was laying under the tree. Dosia runs around the wood pile and the cat runs through it popping out in different spots and smacking him. She was in there with out popping out for a minute and Dosia started to whine. Marley hopped up ran over and did 3 loud barks right in his face, like almost touching noses. Then Dosia put his head down like he was scolded and went and laid on the steps by the door. Has anyone else had their dogs do this? Is Marley just being a grouch cause he's old? They used to run and play together and Marley doesn't seem to want to play with him anymore. He just hangs out under his tree and peeks through the fence Should I be worried about the way he is acting?
