My precious 2 yr old St/Great Pyr fur baby was just dx'ed with idiopathic epilepsy, (cluster seizures) 6 months ago. (we ran all the tests except MRI which Neuro Vet thot not needed and all good) She is currently on Keppra and low dose pheno. Question: We live in New England and just experienced ticks on her first time ever this past week. As we live in a condo, she walks leashed, not in woods or trails. She has not been on any tick/flea preventatives except when 6 months old and had a severe aggressive reaction to Seresto Collar. Called Neuro Vet yesterday as well as regular vet and no answers as to what to use that is safe for my epileptic dog. Pls help me with advice, knowledge and recommendations. Most Sincerely and Thank You in advance.
