So Truffles lives in our apartment she only goes outside to go see her grandma about twice a week and car rides all the time . She has a screened in porch with real grass that she goes potty on and then comes back inside . I have noticed when at grandma's she goes none stop when she's outside. How long should I allow her to play out there? It's already been in the high 80's so I would love to hear from people who deal with hot hot weather because I'm from Pennsylvania and our dogs play allday because its nice out . Sometimes Truffles after playing throws up water because she over does it. I need some opinions on how long she should be allowed to play outside . Thank you
