Get Your Dog Care Questions Answered by Experts ASAP
What age and breed are your dogs?
Are they both male?Neutered?
Is the one that chews the submissive one?
I am sorry you are having trouble.
This may have started as an OCD disorder when the chewer was young.He is trying to comfort himself like a baby sucks a pacifier.
Surprisingly your golden doodle allowed it where another dog would have growled to warn him off.
Bitter apple wont help a bit. You must make the area inaccessible and also teach him a LEAVE IT! command.
Put a sweater on the golden doodle.When the chewer goes for it say NO LEAVE IT. When he stops click a clicker and give him a treat.
Keep repeating till he will stop on command.
and here is a good video on it
Get him plenty of safe chew toys he can have instead of chewing his friend.
Please let me know how things are going.
Warmest best wishes,
