We just lost two of our beloved Rat Terriers, one to liver cancer and, two months later, one to multiple organ failure due to old age. Now we have a little adoptee, Bonnie, one year old, very active, 12 pound Rattie, who was on Nexgard when she arrived. When the month was up, I gave her a Nexgard and she has not stopped itching, biting and licking to the point that she has an area on her left wrist that had pea-sized bumps in it and she has licked the hair off the area. She also, I noticed, has very dry, flaky skin. Has anyone else had a dog react in this way after taking Nexgard? We live in an area with lots of fleas and ticks, even though we have a fenced in yard. Does anyone know of an alternative that won't involve me having to chase this little speed demon down to apply something?
