Not sure if there's another thread on this issue - I did a wee search for CBD in the A&P forum and couldn't find anything so thought I'd introduce it as a topic.
My Irish Setter has been having seizures for 18 months or more and is on a frequency of one fit every 7/8 days with lots of smaller petit mal fits in between.
She's been on Pexion for maybe 6 months now and tbh I'm not sure how effective it is really - this may be because of the form of epilepsy that my dog has. My vet believes that it's not the regular idiopathic type as she developed it quite late (8/9 years) - idiopathic epilepsy normally rears it's head by the fifth year. My vet suspects it may have developed due to a head trauma or a stroke or a brain bleed of some kind.
Recently I've come to the conclusion that the Pexion appears to be having little effect - I've been using it alongside some phenobarbitol in an attempt to lessen the amount of pheno I have to give her. This doesn't mean it wont work for your dog - they're all different obviously.
What I have found some success with - and it's given me some confidence to ease back on the Pexion and hopefully wean her off it altogether - is CBD oil.
She's been on it for just over two weeks now and while it's too early to judge just how much effect it's having on weekly bigger fit I can say with some certainty that it's had a sizable impact on the small petit mal seizures to the extent that I can only think of one day in the last week to ten days when she had any. Prior to the CBD she'd have them most days - you could see her face twitch and she'd sometimes lose her legs momentarily.
Even if the CBD only clears these up I'd consider it to have been a success as although they were quite small they still caused her some discomfort and made her quite hungry and agitated for a while after. I really do think that she seems a lot happier now - I hope it continues and that she continues to improve.
I'll post back in here in another couple of weeks when I get more of a gauge on the impact it's having on the bigger fits - but I'm hopeful that i'll see an improvement.
My vet has also told me of another client of his who's had some success with a spoon of cold-pressed coconut oil every day so I've added that to her food too - has to be worth a go too!
Incidentally, re. pexion - a box of 100 x 400mg tablets is costing me €111 with my vet but I've recently discovered that they can be bought online here -
https://www.petdrugsonline.co.uk/search?searchtext=pexion - you'll need a prescription from your vet but they're almost half price on there at €66 inc delivery.
Hope that all makes sense and that something in there is of use to someone. Maybe someone else has some experience of CBD Oil and dog epilepsy?
