Symptoms of Ticks in Dogs. Ticks often cause symptoms on the skin which cause owners to take a close look at the cause of the symptoms. Once ticks latch onto the skin, they can cause severe itchiness in addition to red and inflamed skin. Dogs which are allergic to ticks may have especially severe skin itch and inflammation symptoms. Pet owners may also notice ticks on their dog once the tick becomes bloated after feeding on the dog and large enough to see. Reactions to tick bites may also cause internal symptoms to develop.
