Found this bike attachment on afitdog.com. Haven’t tried it but it looks pretty cool! It is so important that we get our dogs out and exercise them. So many days our dogs are at home waiting for us to come home. So many days we come home too tired to exercise them (or us). This might make it a little easier. It’s amazing how much happier your dog is when he get out and moves! It eliminates so many behavioral problems too. I might just give this a try.
