DENVER, Colo. - In the summer, it can be tough taking your dog on a walk.
If the heat doesn't seem to make them exhausted, the hot concrete may make them head back home.
However, many dog owners let their pets run through the grass to avoid the hot temperatures on their paws.
The seeds from foxtails can get caught in a dog's fur and paws, which could lead to infections.
The seeds can act as thorns, or a splinter, which can cause problems for the dog's immune system.
Foxtail plants are often found in the western half of the United States.
