We were ouside playing and he was chasing me and he ran to fast past me and was trying to slow down and he slid on the concrete. He then tried to finish playing and I noticed he was limping and he fell. So I brought him inside and then he tried to walk and fell again. I started to panic but he got up and started running around like normal lol. Im going to watch him for the day and if i still see him limping im taking him to the vet if they have any open.
