In Arizona this time of year the temperatures are already reaching the 90's. To help my dog Gator cool off after a hot walk; I like to give him a treat based on the principles of Chinese veterinary medicine.
In Chinese medicine we look at each food as having a specific effect on the body. For example, some foods are "warming", some are "cooling", some help drain excess fluids from the body, and some help to circulate "Qi" (pronounced "Chee") - the life force energy.
Watermelon is in the category of "cold" foods. That is, when you eat it, even if it is at room temperature, it effectively cools the body down. I like to keep a small watermelon in the refrigerator; and offer Gator a few bites after a walk.
If your dog has a sensitive stomach you may want to try a very small amount to start and see how she tolerates it. You could also try a kefir or yogurt (unsweetened, plain) treat. These are cooling foods as well, and often the probiotics help pups with sensitive tummies.
more please! :)
