Fristy, I have read the entire topic below with the title "my dog just had a fit or a seizure" and it was very helpful, however I really need anyones experiences with regard to the side effects of this drug. My dog started displaying symtoms of "fly biting" lask week. The vets diagnosed focal seizures and started him on phenomav straight away. We have been to the vets 3 times since then due to dog developing first a tremor, then weakness in his back legs which comes and goes. Sometimes the weakness is just a wobble, other times he can't stand up. The weakness symptoms started after we doubled his meds and have been getting worse all week. He will be getting a CT scan next week, but from my own observations I'm convinced that the medication is the cause of the weekness (its worse after giving him the meds and then improves a bit until i give him the next dose). Everyone seems to agree that being lethargic is a well known side effect, but what are peoples thoughts or expereinces on mild to severe hind leg weakness that comes and goes?
I hope this post makes sense, I've been up all night with the dog.
