Something strange happened to Scooter Sunday night. We were outside working on the cars all day and had him outside with us, it was a really nice day. I gave him a bath while we were out there too... he needed it! While we were working he was tied by his leash to the shoeing stocks that are sitting outside. He was right next to us the entire time, and had lots of water to drink. We were getting ready to head inside and we were going to walk him around the yard for a little while first. I untied him and we started walking up the yard... I noticed he was "bunny hopping" a little... picking his whole hind end up and hopping as he was walking. I picked him up to make sure he didn't have something in his foot, all checked out fine. But when I put him back on the ground he started acting really strange... he was acting like he couldn't walk at all, lifting his front feet high off the ground and then falling over, his legs were all trying to go in different directions and it looked really scary. I picked him up and he kept moving his legs a bunch then he settled down. I put him back down and he started doing it again... picked him up and carried him almost to the door then I set him down again and he "bunny hopped" for a second and then started running like nothing was wrong. It scared us pretty bad, but he has acted perfectly fine every since, running and jumping and playing and acting normal. I wasn't sure if I should take him to the vet or just wait and if it happens again take him to the vet.
