I want a westie and wondering how much exercise they need
Westies are terriers so they do have a good amount of energy. Puppies of course having more so if you do get a baby westie then I would suggest one or two walks a day, several play times through out the day and a good run in the yard (or park if you don’t have a backyard).
Adult westies are a bit different. Even though they are still energetic they can be couch potatoes also. I would suggest maybe a walk a day (especially if you don’t have a backyard, or if your yard is small), a playtime during the day and just let them run round & chase squirrels in the backyard. That’s what we do with my six year old westie and have done wince my family & I have owned him since he was a year. We also have a huge backyard & have another dog that he is always playing with. Westies love to be outside, and my boy (Josh) HAS to be out with us whenever we even think about stepping outside.
They are great dogs! But please do your research on the breed so you know what to expect. Good luck!
