I am convinced that the squirrels in our backyard have figured out that the deck restrains the dogs and that teasing them is a fun activity! They stay just outside their reach and tease my poor Chis endlessly!
Cosmos is the one who suffers the most, poor guy. He will run back and forth following them during their mind games, to the point where he is exhausted! When taunted enough, he will jump down of the deck to get them. What kind of brain power do these lil rodents have? Surly the dogs have more!?!
