Our three year old mixed breed has had a few episodes of pain in a leg (enough to reduce him to a shivering heap). When we've taken him to the vet they've never found anything and a couple of days of painkillers and he is fine again.
Last time it happened he was in the garden and dh found him curled up in the snow. The pain took much longer to go away (he yelps on jumping up, but is otherwise fine) we had a few vet visits and anti inflamatories for a week or two. The vet said it was maybe arthritis.
I was away at the time and when I came back I noticed that his skin which is normally a very dark colour had gone pale pink (still looked good condition and his gums were fine). The vet said it was just him growing up so I didn't think of it too much, but we were away for a few days last week and on our return noticed that his skin had gone back to it's usual colour.
Are there any conditions associated with skin colour? He is a healthy active dog apart from the pain on jumpng every now and then thing.
