I try to give Lola as much exercise and playtime as she can handle. We all know about overheating, and the summer here in Mass has consistently been hot and humid. My question is, when do you pull the plug on playtime and make your bully take a time out? Lola loves to run around with my parents dog, who is a lab mix, and can certainly outlast Lola. That doesn't stop Lola one bit. She'll chase my parent's dog all day if I'd let her, but i always have to make her take a break. Sometimes I feel like I've waited too long, because she breathes so heavily and it takes her a while to recover. Is there a time allotment, or a sign that you look for to say that's enough for now?
