So out of nowhere, my dog, who will be 7 in May, has become so lethargic in the house. He's eating normal and when we go outside, he's his normal self.
In the house, he used to run up the steps and jump on the furniture to lay down. This weekend, he would gingerly go up and down the steps and last night, he tried jumping on the couch to lay down, but couldn't.
He has had arthritis problems in one paw last year but meds cleared it up. I'm going to make vet appointment but was just out of nowhere.
