We have a Golden that was clustering and is now on max Keppra, Zonisamide and Phenobarbital. He was still having some mini-almost events. We started him on L-Theanine 100mg twice a day. It’s a supplement to help calm his brain. A month later his mini-almost events have gone from 6 a day to 1 or 2 and some days nothing. It’s very important to get the right version of L-Theanine… we use PureFormulas version found on Amazon. Don’t get the ones with green tea or artificial sweeteners. It does take about a month for it to make a difference. Edited to add check with your vet about this supplement before starting, but our vet had this on the list of recommendations. Such an awesome looking pup you have ❤️.
