This evening we noticed that Charlie was limping on his left foot. I had a look and couldn't see anything stuck in his foot or any wounds. I gave it a good feel and a quick squeeze which he did not react to. I put it down to rough play with his 'sister' Lola His foot has now swollen to about twice it's normal size (no futher swelling for about and hour now), but there is still no pain reaction. I have phoned the vet's emergency number and have been advised to keep an eye on it for tonight and if no improvement take him in firt thing in the morning. But what if anything can I do to help with the swelling and comfort?
