It is normal for dogs to have hard bumps after being bitten by ticks. This is because the tick toxins remain in the wound after the dog is bitten by a tick, so hard bumps will appear. When you find a hard pimple on your dog, you need to help the dog clean the affected area. First disinfect it with alcohol or iodophor, and then apply ointment to the area with the pimple.

Tips:

Pay attention to bathing your dog regularly to repel insects, and do not take your dog to play in the grass, otherwise it will be easy to be bitten by mosquitoes and cause skin diseases.
