I have a 5.5 year old Red Cattle dog - he's usually very alert and quite active (ie will run to you when you walk outside) however, in the last week he has been asleep alot and he usually does spend alot of time on his back in the sun, but I've noticed today that he struggles to get up and seems to be really sad. It breaks my heart.
I can't get him to the vet until tomorrow, but I dont know what I can do in the meantime.
Is it possible that he could have some sort of arthritis or an illness?
Sorry, i don't really know what else to do.
