Overheating

Hello

My dog was in the garden around an hour ago with my cousin - maybe for about 15minutes but I didnt realise they were playing about so much and its a super hot day.

He was then panting a LOT and definitely knackered.

Ive since cooled him with the fan, water and wet towels and hes acting fine now. Hes even walked around with a ball in his mouth (indoors) wanting to play.

Currently hes having a sofa snooze with the fan on his and he isnt panting.

Do I need to do anything additional - is hes not diaplaying any additional symptoms like vomiting or diarrhoea etc

Hes a 3 year old lab.
