Today is a very very hot day but there is a little breeze so early afternoon I took Vanilla on a 25 minute walk. She began panting and her walk got slower and slower so I picked her up brought her into the house. The next thing I know she darts straight towards her water bowl, drinks and just collapses. She would not get up right away. She continued to pant for the next 15 minutes even though we were inside with air conditioning on. Now it has been an hour and she's back to normal. I don't think she can handle walking in hot weather.
