Your dog might be allergic to fleas, or rather, the flea’s saliva. When the flea bites your dog, then, it could trigger itching, scratching, rashes, and even difficulty in breathing. The scratching would result in skin infections, hot spots, and other worrisome troubles.
Not only does this cause your pet a lot of pain, but it also creates a daily issue for you as well. Breathing problems would have you rushing to the vet every other day and fearing for your dog’s life. The scratching is unsightly, while the red patches are disturbing to see. Having a regular treatment to prevent fleas and ticks can hence do away with several problems at once.
