Winston hurt is leg. Please send love.

Woke up went to take him out and he was limping. Went to the vet was given Gallprant, said it was for inflammation. Winston is hobbling on the good legs, hates that I “manhandle” him (I have carried him up and down porch steps) but still wants to play with his ball so in good spirits I guess. Any idea to keep him occupied while not being able to fetch?
