I have used garlic on my daschund mix terrie 6 years old for a long time. She had allergies bad. Even her skin turned black. The garlic has really helped her a lot. She is healthy. I will continue using the garlic.
My kelpie/border-collie suffered badly from an allergic reaction to grasses in spring, scratching her itchy skin until she had sores and needed vet treatment (cortisone, I think). Having suffered all my life with sneezing and runny nose in spring, . I had begun taking a horseradish and garlic capsule twice daily which cured me. So I began giving it to my dog, twice daily during spring and once daily for the rest of the year like me. She had no more trouble with itchy skin, or fleas and lived to be 16, suffering only from arthritis in the last couple of years. My new pup is only 5 months old and scratches regularly but not badly yet. I am wondering how old she should be before giving her the same capsules.
