Sometimes the clippers they use when they shave certain areas real short can cause them to itch also. There are sooo many factors that could cause this.
You might try taking in your own shampoo/conditioner for your groomer to use and see if this works. If Dega is still scratching after the grooming appt. then you know it's not the shampoo.
They also spray the cologne, this might be the culprit??
Or the water even...As I said, it could be a number of things.
Also, if you have tried everything, maybe try a new vet and see if Dega still continues this problem.
Good luck.
