Hi everyone
this may be a bit long I'm afraid but here goes.
Took the boys for a run end of last week(thurs I think) and let Asa off as usual.He ran down to his favourite area of rough grass where he usually tries to sniff out small mammals.Anyway  he stopped suddenly and let out a loud yelp,then stood looking at me on 3 legs.I ran down to him and he hopped over to me refusing to put his back leg on the floor.I examined it as best I could and could find no obvious injury...no sore areas. So we turned to go back to the car and within 30 seconds he ran off....100% sound!!!
At manchester on saturday I took him out to relieve himself and he went lame again but only for 4/5 strides.We had only been walking and it was flat.
Today we went to the park and the same as last thursday only didn't seem quite as bad...no yelp.
Now I am totally confused...he is totally sound except for these 'instances',no sore areas and almost instant recovery.
Any ideas what it is??
Treatment?? Am intending on doing a couple of weeks lead only exercise and gradually building up from there....
off to work now but will read any replies whilst there..just can't post!!

Is a car journey involved before each of these incidents? Could it be cramp? I would rest him totally.

Wheeler has done this before. He went lame on 1 paw but after an hour he just perked up! It could mean that something was stuck and fell out but we looked and couldn't find anything in his paw. I was told by a friend that the whippet in him may be looking for sympathy so maybe this could be the case? Sorry I can't be of any more help!
