This is not just the case with dogs, but humans also, if you can chat with a person who has a professionally diagnosed OCD, they will tell you at best, management is their best friend.
There often is no cure.
K9: You mean of course, the worst case you have ever seen, not the worst case that has ever been seen.Ive seen the worst case of OCD ever,
K9: One dog (if it was cured) does not constitute a bankable treatment, no different really to the fact that some people take herbal medicines to cure cancer & it has worked.including human ocd in a dog. Who, 6 wks into treatment with said SSRI's, was completely released from his torment of chasing his tale to the detriment of his health. He would be triggerred in this behaviour by his shadow on the ground, he'd look around for what was causing the shadow, see his tale, then chase.
FOR 15 hrs A DAY! Non stop, till the sun went down, and his shadow went away. Not stop to drink, eat, interact because he could not. And completely cured with SSRI's.
It isnt as simple now though as cancer can be cured with herbal medicine.
