Prepare for unexpected vet bills
If you live in a city or an apartment building in Massachusetts and you need something dry to entertain and exercise both you and your dog, why not take the stairs? Depending on how many stories your apartment has, you could get a great workout just walking up and down the stairs.
Play hide and seek with your dog. Hide in another room and then call them to find you. Your dog will have to use all their senses to see where you are, and will expend energy rushing around trying to find you.
