There are some different situations happened between dogs and their collars, and we cannot exactly answer this question.
Some people have noticed that their dog freaking out when they take his or her collar off. If something like that happened, you need to look beyond the act of removing the collar to discover the cause of this excitement.
Before you try to fix the behavior, check to see the collar fits him correctly. Your dog’s collar could simply be too tight; make sure you can comfortably fit two fingers underneath, between the collar and his fur. It should be snug enough that it stays on, but not so loose that he or she can snag it on something and get caught.
Your dog’s behavior is often a reflection of your actions. Your dog may associate collar removal with freedom, or indeed the end of playtime; or it may simply be that he hates being touched.
Dogs learn most behaviors through reinforcement. It’s possible that you encouraged your dog’s freak out behavior, accidentally of course. The next time you reach down to remove the collar, don’t touch your dog, or even make eye contact, until he holds still. He needs to learn that his collar isn’t going anywhere until he relaxes.
Also, there is a situation when your dog doesn’t like to wear collar, maybe even hates it.
You just leave the collar on your puppy until he gets used to it. Make sure you have it sized properly, but besides that you need to just sit back and let your dog get used to his new collar.
Shock collars are often used to curb a variety of stubborn and unwanted behaviors in family dogs, from excessive barking to food aggression, as well as to train pups to stay safely within a property line or to stick close. These collars are not intended as a punishment. The theory is that your dog will associate the unwanted behavior with an uncomfortable shock and stop doing it until they no longer require the reminder.
Using a shock collar doesn’t make you a bad pet owner, and it doesn’t mean you are torturing your dog.
