Dogs and cats can get arthritis just the same as the rest of us.
But they can't communicate how they feel as easily.
Not all animals can handle medication so there are other, holistic options.
Another thing to look at could be how much weight your pet carries.
Being overweight can cause more pressure on the joints, leading to more inflammation and more pain.
Some other solutions include laser therapy, massages and changes in diet.
Your best bet though?
Talk to your vet.
That's what they're there for.
