<human>: I came to visit my mother today and brought my dog. My mom's dog (Dakota) never gets exercised. I took her on a long walk with my dog when it was about 80°F and we've been home in the AC for almost an hour. She and my dog have been off-and-on playing but have been calm for about 20 minutes. I just noticed Dakota is panting very heavily and has very hot ears and feet. She will not stop panting and just seems to be overheating to an extreme amount. There are no other symptoms of possible heat stroke besides this. 

Everybody else in the house is asleep. I don't know Dakota well; I don't know if this is normal for her. If I were in my own home I'd give her a cold bath but I'm in my mother's home and she's very upset about some things right now, and if I wake her up by bathing her dog she will flip shit and I will have to go home (I was given a ride here earlier, a taxi ride back will be about $100 that I don't have). Also tomorrow's my birthday celebration -- a bunch of family are supposed to come over and that will all be cancelled if my mother gets any more stressed out. 

Should I be worried? Do you have any ideas on what I can quietly do to help Dakota?

Can you condense the text into three sentences or less?
<bot>: Dog who never gets exercised went on first walk tonight and is extremely hot and has been panting heavily for the last hour despite being in AC. Is this a minor heat stroke or other emergency?
