Dog Scratching
It can be stressful to watch your dog scratch over and over. Here’s what scratching can mean, what you can safely do at home, and when it’s time to call a vet.
When to Call a Vet
Go to the ER now
- ● Your dog is having trouble breathing, has facial swelling, or suddenly breaks out in hives after a sting, medication, food, or other exposure.
- ● Scratching comes with severe swelling, bleeding, large open wounds, or skin that looks raw and painful.
- ● Your dog seems very weak, collapses, or is extremely distressed while scratching or after a possible allergic reaction.
- ● There are signs of a serious ear problem along with scratching, such as severe pain, loss of balance, head tilt, or repeated crying out.
See a vet within 24 hours
- ● Scratching is intense, nonstop, or keeps your dog from resting, eating, or acting normally.
- ● You see red, inflamed, smelly, moist, crusty, or infected-looking skin, or your dog is losing hair from licking and scratching.
- ● Your dog is scratching the ears or shaking the head often, especially if there is odor, discharge, or sensitivity around the ears.
- ● You suspect fleas, mites, mange, or another parasite, especially if pets or people in the home are also itchy.
- ● The scratching lasts more than a day or two, keeps coming back, or is getting worse.
Watch at home, call if it worsens
- ● The scratching is mild, brief, and your dog is otherwise eating, drinking, and acting normally.
- ● You can link the itching to a minor trigger like dry skin or getting dirty outside, and it settles quickly with gentle bathing and monitoring.
- ● There is no redness, rash, odor, swelling, discharge, or hair loss.
- ● Your dog is not obsessively chewing paws, rubbing the face, or scratching one area over and over.
Common Causes of Dog Scratching
Fleas and flea allergy
Fleas are one of the first causes vets try to rule out in itchy dogs. Some dogs are so sensitive to flea saliva that even a single bite can trigger intense itching, especially around the tail base.
Environmental allergies
Pollen, dust mites, molds, and other allergens can cause allergic skin disease in dogs. Scratching may be seasonal at first and can affect the paws, face, ears, belly, and underarms.
Food allergy
Food allergy can cause year-round itching in some dogs. It often shows up with itchy ears, paws, recurrent skin infections, or ongoing ear problems.
Skin or ear infection
Bacterial and yeast infections can make dogs very itchy and can happen on their own or alongside allergies. You may notice redness, odor, greasy skin, crusts, or brown ear debris.
Mites and mange
Mites can cause severe itching, crusting, hair loss, and skin irritation. Some types are contagious to other pets, and certain mites can also make people itchy.
Contact irritation or anal gland discomfort
Shampoos, grooming products, grass, or other irritants can make skin itchy. Some dogs also scratch or chew near the tail end because of anal gland irritation or discomfort.
What to Do at Home
Mild scratching can sometimes be watched closely at home, but repeated or intense itching usually needs veterinary attention because scratching can quickly lead to skin damage and infection. Focus on preventing self-trauma, looking for simple clues like fleas or ear debris, and keeping your dog comfortable while you arrange care if needed.
- Check your dog’s skin and coat for fleas, flea dirt, redness, scabs, hot spots, hair loss, or areas your dog keeps returning to.
- Look at the ears for head shaking, odor, redness, discharge, or sensitivity, since ear disease commonly triggers scratching.
- Use an e-collar or other vet-approved barrier if your dog is scratching or chewing enough to create open sores.
- If your dog recently got dirty or may have environmental allergens on the coat, a gentle bath with a dog-safe shampoo may help rinse irritants away.
- Keep up with regular flea prevention exactly as directed by your veterinarian, since flea allergy can flare from very little exposure.
- Call your vet if the itching is strong, recurrent, affecting the ears or paws, or causing broken skin, odor, or hair loss.
