Hi! Sorry to hear poor little Jamie‘s confined to crate, I know from experience what a nightmare that is!
I don’t have any experience with white noise although after reading somewhere that classical music helps calm dogs, I did used to have it in the background while I was getting Humphrey used to the grooming table and it did seem to help.
Most positive dog training is based on association, so I could well imagine you could continue to use the white music as a calming signal, by playing it when he‘s naturally relaxed and happy? It certainly can’t do any harm to try.
It‘d be interesting to know how you get on with it, it may help others dealing with separation anxiety.
Lots of for the little patient, hope he‘s out and about before too long. Do keep us updated!
Thanks for your kind comment. The recuperation is long, at least two months of very restricted exercise (for an 18 month high energy/excitable pup!). He's still in the first week post surgery and acts as though it never happened. Good in one way, but hell on trying to keep him from injuring the surgical leg. He's still in a cone and this morning was scratching at the cone because of itchy ear with his bad leg
His calmness when I left him to go outside and talk to someone on the property which normally he would react to was notable with the white noise on. I don't know whether it was coincidental or a true effect. Last night I put on a meditation loop for sleep which is nicer than the static sound of the white noise, but I'll continue with white noise to see if it really is effective. Such a difficult process, this post orthopaedic surgery on a young dog. But best to get it done and fading into the past.
