Here in Kansas we're having a mild summer, which is super great for me, because I just moved from south Florida... it's a relief! Our dogs stay inside all day. We live in an apartment so they just get a few walks a day and don't ever get to stay outside. However, my boyfriend works at a kennel, and he would usually bring our doberman to work. It lets him get some socialization, and he gets so excited and gets to bark and play rough with bigger dogs (our other dog is a little Min Pin/Chihuahua, so he can't be too rough at home). He really loves it, and he gets to go for free so it's great for us too. It gets hot, but the dogs are only ever outside for like 15 minutes at a time so it's okay. He hasn't been able to go lately because he got giardia and is still recovering, poor thing is getting stir crazy in this apartment! Where my boyfriend used to work (down in Florida), the kennel had a huge kiddie pool outside and the dogs would splash around in that whenever they were outside.
