Hi everyone! I have an 8 year old 1/2 silky-1/2 chihuahua. A little bit ago I heard something on the floor and he had both front legs out to his sides and was on his stomach trying to scoot because he couldn’t get up. He was breathing hard and I could tell he was very upset because he couldn’t do anything. After about 2 minutes of petting him and talking to him he got back up and acts fine. It really scared us. Any ideas on what might have happened? Thank you so much.
