What is a common sign of harvest mites on dogs?

A common sign of harvest mites on dogs is the presence of red inflamed patches of skin. Harvest mites, also known as berry mites or red mites, can cause an allergic reaction or dermatitis in dogs. This reaction typically manifests as localized inflammation, redness, and itching where the mites have attached themselves to the dog's skin. As the mites feed, they can irritate the skin, leading to visible signs of inflammation.

In contrast, symptoms such as excessive barking or an increase in stamina are not directly associated with the presence of harvest mites. Swollen paws may occur for various reasons, but it is not a specific sign of harvest mites. Understanding the specific symptoms associated with parasitic infestations like harvest mites is crucial for diagnosis and treatment.
