ok, there ARE easy and effective home remedies for ear infections and hot spots.
For hot spots, apply a flea repellent (frontline) to assure no fleas -- you should be doing this anyhow, and use "super ivy dry" from your local drug store. Put on three times a day. Gold bond powder is also good. A normal hot spot will go away with this treatment (there are more serious ones that require steriods and antibiotics, but these are rare).
The itchies -- try a grain free food.
For ear infections, there is an easy and cheap solution!
BLUE POWER EAR SOLUTION
16 Oz. Isopropyl Alcohol
4 Tablespoons Boric Acid Powder
16 Drops Gentian Violet Solution 1%
Mix together in alcohol bottle and shake well.
You will also need to shake solution every time you use it to disperse the Boric Acid Powder.
TREATMENT: Evaluate condition of ears before treating and if very inflamed and sore do not attempt to pull hair or clean out ear at all.
Wait until inflammation has subsided which will be about 2 days.
Shake the bottle each time before using.
Put cotton balls or similiar absorbent material under the ear.
Flood the ear with solution, (gently squirt bottle), massage gently to the count of 60, wipe with a tissue.
Flood again on first treatment, wipe with a tissue, and leave alone without massage.
The dog will shake out the excess which can be wiped with a tissue, cotton ball, etc as the Gentian Violet does stain fabrics.
The SCHEDULE of treatment is as follows:
Treat 2x per day for the first week to two weeks depending upon severity of ears
Treat 1x per day for the next 1-2 weeks
Treat 1x per month (or even less frequently, depending on the dog)
All of these ingredients should be available at a pharmacy.
The Boric Acid Powder soothes the ear.
The Gentian Violet Solution is an anti-infection agent.
The solution appears to work well on any and all ear problems from mites to wax to canker.
After the 2nd or 3rd day you can clean out the ear with a Q-tip or cotton balls.
The success rate for this treatment is 95-99%.
If an infection seems to be remaining in the treated ear after the above course of treatment, you may also have some Pseudomonas bacteria in the site.
This can be eradicated by using a gentle flush of raw apple cider vinegar and wateR(warm)
Use 2 Tablespoons of vinegar to one cup of water, 2 x per week.
They have found the Blue Powder Solution to be effective for treating fungus-type infections on the feet and elsewhere on the dog, for cuts on dogs or people, and for hot spots.
Remember it is for external use only ..so be careful not to get into the eyes.
sorry to say but he will need the vet's assistance as they have antibiotic's for the dog to cure the yeast infection inside the ear canal.
There are not home remedies unless you would have cleaned out the ears starting from when you got him with solutions found at pet stores.
The yeast builds up inside and it may not smell but it needs to be treated before it gets real bad .
As far as the chewing on the feet that is what is called allergies and I think he has that.
if his skin is sensitive then I would change his food as food is the first to cause a dog to bite the skin or lick the skin or scratch.
Food allergies are sometimes hard to detect as the dog eats the food and he enjoys it and he seems healthy.
Look to make sure your dog food does not contain any of the following as over time of eating these they cause problems in dogs
Try putting your dog on a better brand and if you are on a low income you can still get good dog food like Canidae which is about $34 for a 33lb bag and it is good for the dog.
other brands will be more expensive but Canidae is cheaper but still good food.
When you scratch a dog most of them have spots that will make their leg kick it is funny but all dogs have that spot.
Your dog needs to be diagnosed and prescribed medication by a licensed vet. You also need to have your vet run a thyroid panel. As stated in another question, you said that your dog is 117 pounds. That is obese. A male Malamute should weigh 80-95 pounds.
