Paw licking, itching and skin chewing are often signs of allergies. You may see red staining to the fur in the licked areas or raw spots where the dog chews itself.

Itching around the tail area is often a sign of a flea allergy.

The skin itches from allergies, the dog licks and chews trying to soothe the itch, making the skin raw and allowing other infections to set in which may itch even more.

Dogs can develop allergies to foods, even ones they eat all the time, and to inhaled items, and contact allergens such as rug cleaners, cedar beds, or chemicals including lawn chemicals or even flea bites.

You might want to try a different dog food that has no ingredients the same as what you feed now. Diets of Fish and Potato, venison, or rabbit etc. where the protein source is new and there are no grains in the food can work for many dogs for example. Another option is the hypoallergenic diet from your vet Hills ZD. Changing food does no good if you feed the same ingredients. Remember food changes have to include all treats and supplements. It can take 8-12 weeks or more before you see results in skin and coat.

If this is an inhalant allergy, which often shows up only seasonally, you may find using a HEPA air filter in the room the dog uses most and wiping the dog down with a damp towel when it comes in helps reduce allergen exposure.

You might want to see if some plain Benadryl helps with the itching. A common low dose is 1mg per pound of dog every 12 hours. Do check with your vet about using a med but this one or another may help him a lot. If you choose to use that please read here about cautions

You may want to consult with your vet and consider doing allergy testing.

Or ask your vet about using Temaril-P to see if that works

You can try a Chlorhexiderm shampoo from the pet supply store in case the problem is a bacterial skin infection. Malaseb is another good one to eliminate yeast from the skin. Follow directions on the bottles if you try one.

Dogs can have low thyroid level issues and that can trigger skin allergies. The vet can check for that with a blood test.

If your dog is not on a flea prevention that might also help. Just one flea bite can make an allergic dog itch all over. If that is the problem then Frontline could resolve a lot of the reactions for you.

Some people find their dogs do better when they are given omega 3&6 fatty acid supplements such as Derm Caps or Linatone from the pet supply store.

If your regular vet is not able to help you then you may want to see a veterinary dermatologist and this page may help you locate one if your vet can't refer you to one

doesnt really help looks kind yuckie maybe because he is chewing it. There is a small hard bump under his skin on his butt basically right on top of the butt. what is it? could that be causing it?
Expert:  NancyH replied 7 years ago.

If this is around his anus area then it may be an inflamed anal gland.

If this is on top of the tail area as you described originally this is probably a reaction to allergies and most likely flea bite allergies.

The chewing causes a break in the skin leading to infections.

The lump and the skin issue can be from that.

I'd say what you need to do is have your vet look at this in person and if your dog is not on flea prevention you may need to do that.

For any sore spots you can try cleaning the area with betadine iodine solution and then using Neosporin ointment on it..

You can see if using benadryl as mentioned above stops the biting and chewing.

the bump is really like on the top of the butt right before the tail
Expert:  NancyH replied 7 years ago.

Then that is the area for flea bite allergies or an infection from chewing the area.

Unless by 'butt' you mean the area under the tail by the anus?

he is on frontline every month this is bigger then a flea bump. Could have nothing to do with it, most likely allgeries as you said he is prone to hot spots on his face and chews his pads which i have been told goldens do.
Expert:  NancyH replied 7 years ago.

Then it may be an allergy to something else.

You can try the Benadryl for the itching and the topical care for any open sore areas.

But I'd consider seeing your vet as they can give meds to stop itching, help the skin repair and antibiotics if needed.
