Just writing a comment about my Chihuahua-Terrier dog, Julio. Heartworm meds are toxic to our animals. My beloved pet would have periodic seizures. When I stopped the heartworm medication, the seizures stopped. One Vet had him on them, another said why are you giving them to him? Does he have heartworms? He said he would not give them to him. I was grateful that it wasn't about $$$$, but about my pet. If an animal gets heartworms (most indoor door pets are not exposed to mesquito larvae,) which causes heartworms. A small amount of VCO in their diet will provide essential fatty acids, and is a natural cure for parasitic host. During hot summer months, I use 1/2 tsp. of Cloud Nine herbal dip in 16 ounces of water in a sprayer bottle to repel fleas, or mesquitos that would otherwise zoom in on my pet. You have to be diligent. Shake the bottle each time, and apply before taking your pet out.(be sure to apply to their undercoats, and paws too) A good brushing each day, and using the spray will help too. I hope this is a helpful tip for all pet lovers.
Thanks, and God Bless!
