Hot spots are inflamed areas on your dog’s skin that he excessively licks, bites and scratches at until they become gory and infected. Although they’re more common in certain breeds — Labs and goldens seem particularly susceptible — any dog can get them.
What Causes Hot Spots?
- They aren’t caused by heat, although extremely hot weather may certain trigger them.
- Some skin infections can cause hot spots, but it’s more likely that the culprit is a bad reaction to insect bites, an injury or surgery, environmental injuries, poor-quality food — or even boredom. In other words, hot spots are a secondary symptom of a larger problem, and until you determine what that problem is, the hot spots won’t go away.
- In the case of insect bites, you may not even know there’s a problem until you see the hot spot. Although fleas are usually the most common offenders, spider bites and bee or wasp stings can also trigger hot spots.
- Any kind of injury can be the source of the hot spots. When dogs are in pain, whether from a surgery, scrape, puncture or break, they tend to lick the area incessantly, which is why they’re sent home from the vet in the “cone of shame.”
- Environmental allergies, especially reactions to grass and pollen, can cause itchy skin and, in turn, hot spots.
- Poor-quality food is probably the second most common source of hot spots (flea dermatitis is the first), but it’s also the easiest to control on a long-term basis.
- As for boredom, bored dogs act out in all sorts of unpleasant ways. If your dog is too much of a gentleman to pee on your bed or destroy the sofa, he may try licking himself to death to get your attention.
Infection usually sets in after the dog has irritated the area, turning the hot spot into a serious wound. Then the dog will lick the infected area, further worsening the hot spot.
Left untreated, hot spots can grow quite serious, so if you notice one beginning to form, treat the area immediately.

Fortunately, hot spots are easy to identify:
- You’ll see a red, oozing area that looks like an open wound, usually with hair missing from the area.
- You might also notice pus.
Hot spots can develop extremely quickly, often in as little as 1 day. If your dog has longer hair, you might not see the wound right away, so pay attention if you notice your pup licking the same area over and over.
Hot spots can be painful. Because dogs often react to pain by biting, be careful when handling him or touching the inflamed area. If he starts to growl or show his teeth, you may need to muzzle him before you can treat him.
If you notice a hot spot developing, take your dog to the veterinarian, especially if it’s the first occurrence. Without treatment of the underlying cause of the problem, the hot spots will continue to grow and possibly spread.
Your dog will probably need a round of antibiotics to heal or prevent infection as well as an antibiotic salve to sooth the area.
The first thing your vet will do is shave the area so the wound can dry out. I would not recommend doing this yourself, as your dog may need to be sedated first.

Next, the vet will clean the area thoroughly and let you know if your dog needs antibiotics. He most likely will, if not to clear up an existing infection then to stave off an impending one. Your vet should also advise you to apply a triple-antibiotic cream and a topical drying spray 2 to 3 times a day.
Keep the area clean and as dry as possible. Bathe your dog with a soothing shampoo once a week, and apply cool compresses a few times a day. Tea bags work especially well for this. A hydrocortisone cream can also help.
After the hot spot heals, there is no guarantee that your dog won’t chew himself raw again. Instead of treating each new instance, try some of these tips to prevent more hot spots from recurring:
- Add a fish oil or omega-3 supplement to his food, which will improve his coat and prevent itchiness. After about 1 month, you may see a noticeable improvement in his fur.
- Have your dog’s thyroid checked once a year. Hypothyroidism is common in many breeds. One of the most recognizable symptoms is a rough, unhealthy coat prone to skin problems. Hypothyroidism is simple to treat: a twice-daily doze of Soloxine or another thyroid-elevating prescription drug, all of which are inexpensive.
- Bathe your dog weekly with a skin-soothing shampoo. Don’t use human shampoo, which doesn’t have the right pH balance for dogs. If you notice that frequent shampooing is drying out your dog’s skin, switch to a twice-monthly routine.
