Henri is 11 and over 100 pounds. He is arthritic. Yesterday he was outside running around just fine then last night he couldn't up. He will not put any weight on his left back leg. He is having a very hard time geting up (sometimes he does have a hard time on the floor, but not usually on the rug) I'm not sure if it is the hip or the leg itself. I am going to give him some aspirin to see if it is just pain causing it or if it is the hip or leg not working. I would love other suggestions. Vet is in the future, but I can't get there today and since I lost my FT job in Feb I really can't afford it either and hoping it will just get better in a day or two. I've been having a fairly large vet bill just about every month lately. Thank you!!
