I tend to be conservative with things like this – I will put a dog with a sore limb on crate rest for a week to see if it resolves. If it doesn’t, we head to the vet. This means on leash when in the yard for toilet, no jumping in the car, no jumping on furniture. Just crate or on a cushy bed on the floor.
Things to do: check paw pads, check nails (most people keep dog nails WAY too long, so if you can hear them clicking, it’s time for a nail trim…and then do them twice a week until they’re short, and weekly to maintain). I also move the limb and gently massage to see if there’s any sort of soft tissue soreness.
Hello,
There are a few things that this might be.. diet,, maybe try a different food, one that is made for cats with sensitive stomachs, intestinal parasites ( this is determined by sending a fecal sample to your vets office for analysis), or a disease of the gi tract… maybe even bad teeth? My point is that this is a case where a veterinarian should be consulted to help rule in or out, some of these.
Good luck.
