Update. We really checked his leg and paw last night. Cannot find a thing. This morning he still favors his paw and leg and walking on 3 legs but he tries to use all 4 once in a while. He wanted to go for our morning walk.
I took him just a real short ways, a few feet. Since it is a 4 hour trip to the vet I am going to wait a day and see if he improves, heck he walked down the embankment to the creek also this morning without crying out in pain.
Thank you all for the prayers. (((HUGS))) Will update later.
Carefully look *between the toes* as well as on the pads for slivers, cuts, puncture wounds, etc. They can get well up in there and not be seen.
Is there any swelling? If no swelling and he continues to use the foot more, it's probably just a mild strain. I would limit his activity while this works itself out.
Another good idea would be to give him a nice Epsom salt and warm water soak. That will relieve pain and swelling, and if there is a sliver or splinter it will draw it out.
But if he is still limping tomorrow, I would bundle him up and head for the vet (I will never complain again about our vet being 45 minutes away!)
Thanks ColdOne. How old is Fredd?
