Prickly pear cactus is also used for medicine. Prickly pear cactus is used for type 2 diabetes, high cholesterol, obesity, alcohol hangover, colitis, diarrhea, and benign prostatic hypertrophy (BPH). It is also used to fight viral infections. In foods, the prickly pear juice is used in jellies and candies.
Drooling is usually caused by excess saliva in the mouth. Medical conditions such as acid reflux and pregnancy can increase saliva production. Allergies, tumors, and above-the-neck infections such as strep throat, tonsil infection, and sinusitis can all impair swallowing.
Don't always assume that a drooling dog is necessarily excited, as a handful of different things can lead to salivation. When your dog drools, consider what might have caused it. If you rule out excitement, it might mean the room is too hot and you need to turn the air conditioning on.
