What summer products protect my dog's paws, coat, and repel bugs?

For days where it is very hot, you do want to avoid taking your dog for a walk at the hottest parts of the day (mid-day) especially on paved areas as your dog's feet can get burned. They do sell dog booties that you can put on your dog's feet to help protect them. There are many different companies that make these, one example is https://www.amazon.com/HiPaw-Breathable-Dual-Boots-Protector/dp/B01HS2M7FI/ref=sr_1_7?s=pet-supplies&ie=UTF8&qid=1496836452&sr=1-7&keywords=dog+boots. If she has no skin/coat issues, just a gentle oatmeal shampoo is fine for bathing when needed. Most dogs do not need frequent bathing unless they are getting very dirty and bathing too often can dry their skin out. I wouldn't bathe more than every other week unless needed. You can follow this with a creme rinse. I like https://www.amazon.com/Virbac-Epi-Soothe-Shampoo-8-oz/dp/B002CZHYPA/ref=sr_1_1?ie=UTF8&qid=1496836697&sr=8-1&keywords=virbac+episoothe+shampoo and https://www.amazon.com/Epi-Soothe-Cream-Rinse-Conditioner-Relief/dp/B0056EAJZQ/ref=sr_1_fkmr0_1?ie=UTF8&qid=1496836716&sr=8-1-fkmr0&keywords=virbac+episoothe+creme+rinse. Toys could include filling a kong with wet food and freezing it before giving to your dog, or offering ice cubes or chicken broth/beef broth frozen into cubes, as well as frozen baby carrots. For parasite prevention, if flies are a concern then I would consider products such as K9 Advantix II, Vectra 3D if these products are available where you live. If they are not, I would ask your vet what products are available where you live for these issues.
