Please see your local Veterinarian to rule out mites or fungal problems with your canine pal. This can be something your VET needs to deal with: Allergic Alopecia or Endocrine Disorders -Hormonal Imbalance need to be addressed.
I AM HAPPY TO WORK WITH YOU ONCE YOUR LOCAL VET HAS RULED OUT ANY SERIOUS ISSUES
After you have ruled them out then it's possible your pet is experiencing hair loss due to seasonal alopecia.
Here are a few natural options that I have had great luck with.
1. Add Flaxseed oil to the dog's diet -- 1- 2 tablespoons of flaxseed oil with your dog's food to restore lost hair and prevent further hair loss. You should see results in about 30 days
2. NuVet Plus Supplement TREAT - Most of my clients at 1 to 1.5 NuVet Plus wafers or Powder treats per day .. LIVER flavor and Made in the USA - ( you should start to see results in 30 days )
Helps to repair the skin, grow new fur/hair, and strengthens the immune system to protect against allergies & free radicals & ( environmental hazards )
