My dog is almost always on edge, like most dogs he's completely spoilt but as we had him from a rescue centre he's got issues. He had a form of distemper as a pup (we had him when he was 3) that left him with a bit of a head tilt but other than that he's a healthy 7 year old Collie X.

So my question is this, do you know of some sort of herbal remedy to relax him a bit? I don't want him vegged out just something to take the edge off so he isn't on edge when one of the family is out of his sight.

I've mentioned before on her about Zylkene, I've used it on my cats on recommendation from my vet. It's also available for dogs. You can get it from the vets or buy it cheaper online. You don't need a prescription so it's easy to get, and in my experience works well. It sounds like just the thing you are looking for so it might be worth a try.
You can use it short term, or long term. Just open the capsule and sprinkle on food or water.

Just in case you cant get hold of zylkene-My vet didn't have zylkene and amazon wouldn't deliver it to Ireland for some reason. He did have kalm aid, its a gel that you can put in their mouth or food. I got it for cats but it comes in a doggy version too. I must say its been very effective for the cats I could get it into, they just zonk out like a teenage stoner with no bad after effects. He said he got lots of great reports from nervous cat and dog owners around Hallowe'en with fireworks etc

I'll look into those thanks.

I found Bach's Rescue Remedy effective with my rescue dog.

DAP products are good too.

Both can be used continually without a sedative effect. You'd probably need something stronger for a dog who gets very stressed at fireworks for example.
