Possibly being a hypochondriac here, but after a long day at the beach our Jack Russell Charlie has been whimpering, wandering around the floor and looking lost which is pretty unusual. After a long run in the day he normally sleeps the whole evening but I just tried to pick him up and he was obviously very uncomfortable and whimpering. This is really odd, he normally likes being picked up and petted, but this time just wanted to be put down ASAP.
We've only had him a year (he's 2 years old) so I'm not sure what to think ... anything to get checked out tomorrow (Sunday)?
