Query: Dog Repellent

I had researched for the best product to use on areas inside and outside to keep my now 5 month old Golden Retriever from chewing on everything and bought this product. Either my dog is one of those who this doesn't affect or the product doesn't work. It made him more aggressive on the items I sprayed. I would be reluctant to recommend and should I tried a sample first instead of buying a gallon.
