However, there should be precautions taken if your pet has their own kennel and/or crate.  This is their place of sanctuary but accidents can happen.  Accidents have happened to pets that were in there kennel and/or crate and strangled themselves.  Trying to turn around in their quarters that are too small is a dangerous situation.  The size should be measured according to the size of your dog.  Their tags or collars can hook on something and cannot get loose.  This is not something you as a pet parent want to see.  Pet parents need to be aware of such a problem, so a dog safety collar, especially a dog breakaway collar should be part of their accessories.  It is not such a big deal to have several collars anyway.  Use the breakaway collar when they are in there kennel/crate, or even wear it around the home, just in case.  Dog breakaway collars are affordable and could avoid a catastrophe, but these types of collars are not be used to socialize your dog or out for a walk. They may become excited over other dogs or even sometime humans and break away.  Dogs can detect danger. Depending on the surroundings where they play or wherever you feel comfortable will relieve the pet parent from worrying about the safety of their dog.   Seems as though there are precautions on everything these days, so by using the correct dog safety collar at the appropriate times, your pet will be safe.  One other thing to consider is if your dog’s eyesight is not as good, a lighted collar is sure handy for walking your dog at night, and vehicles will be aware of you and your dog.  Be Happy!
