Is he injured?

This is the second time in about a month that I have had to pull Dylan out of Flyball Practice. I'm not sure what is going on.

A month ago Dylan started limping during practice. I pulled him out and rubbed him down and stretched him out. I gave him some Arnica and by morning he seemed okay. We were headed to the holistic vet the next morning with Leon so I brought Dylan along and she checked him and watched his gate. She couldn't see a limp so we figured he must have just twisted something and seemed to be feeling better.

Last night, he was messing up on his box turn. He's been turning wide sometimes and I think it's because of the training prop. I asked them to move it out. I don't want him learning to turn too wide because of the prop. First turn without he prop was totally messed up. Then I noticed that he was favoring one leg. He won't put near as much weight on his right leg. He's spending a lot of time standing a little bull legged. I pulled him out, rubbed him down and stretched him good. Gave him some Arnica last night but this morning he was still favoring that left leg.

I can't remember if the first time it was the right leg that he was having an issue with. I need to call the vet today and see if they have it in their records.

I hope we can figure out what it is. I don't want my little boy hurting. Paul believes it's just a stubbed toe but I am not sure if that is the case. I have a feeling he's twisted or tweaked something in that leg that needs some time to heal.
