“This product had adverse affects on my 2 y.o kelpie after continued monthly use. She has lost stamina and pants more readily than previously -something not addressed in your blog article on panting. (This Petstock article was reviewed for accuracy by Dr Melanie Hill (BVSc), an Australian-registered veterinarian). On further investigation, other owners have reported similar effects on the nervous system of their kelpies. Look up Princess & Goose for the end stage effects of Nexguard on their kelpie. I'm glad I saw the signs and have stopped NexGuard Spectra even though it was a convenient product.
Hope this helps spread awareness.”
