At the time of writing this I can hardly describe the weather as summery, (it's pouring with rain) however by the time I set it to post I hope it has brightened up and therefore ensures this is a seasonal post!
The PDSA have created an excellent holiday health guide for pets which you can download here.
Also, please remember to never leave your dog (or any animal) in the car during this hot weather. Have a look at this excellent article and find out how you can support Dog's Today's campaign. Make sure you tell your friends as well, especially if they have cars as there are some stickers you can order which are perfect for reminding other drivers to be careful with leaving their pets in cars.
