I have always kept my dogs in their collars 24/7 I just feel happier that if they escaped they would have tags on them. With new pup who I am hoping to show I am unsure as what to do ? currentlyI take it off most times in the house but am really worried particularly with a busy family of young adults that a door left open could spell disaster.People dont think dog all the time despite living with them for25 years !
Any suggestions I dont want to ruin her coat

You could always take her collar off at night, when you know she's secure.

Thank you that would be better than during the day Dont want you to think we are irresponsible its just I worry that a door could so easily get left open and my  gsd opens them himself. Thank goodness not the front door 

Mine are 'collars off' at home but if we are staying with family or friends (with a couple of exceptions) they keep their collars and tags on all day and, as someone else has suggested, I just take them off at night.  As long as they are supervised I use loose fitting all-fabric martingale collars like Lupine or Earthdog

The other advantage about a puppy with no collar on at home is that you can't just rely on towing them around to do everything.  "On your bed", sit, stay, come "give me that sock" etc all have to be reward based instructions as you've no other option!! :)

good point dogs a babe I have to confess on occasion that is what I find myself doing so I guess thats an advantage

:( Then correct myself she is very sensitve about her neck anyway and not very keen about being on a lead. I can see her as one that would prefer to walk without one. (not happening !) so Ineed to take care

Mine are all shown and they wear their round leather half check collars and tags 24/7. 

The almost 5 month pup has an adjustable Braid half check until her neck is of adult size and I have her new leather collar ready waiting.

I can send you a pic of the collars.

Thank you brainless yes please I will pm you with my email

When I kept a collar indoors on my first Malinois it really marked her coat, no matter what type. Then two youngsters I had nearly died as they decided to play one very early morning, one got its mouth caught in the other's collar, and if I had been alone at home, I am 100 % certain one would have died. It was stuck so hard in the mouth it was pouring with blood from the mouth and nose, the other was being strangled -and both were panicky enough to not stay still even the slightest, kicked and screamed etc, so I could not get the collar off. Luckily I had both stepchildren staying and it took all three of us to get them still enough to get the collar off. Never again -it just isn't worth the risk.

Should any dog escape I'd also worry the collar would get stuck on a bush or branch or whatever and strangle them that way or trap them. I know somebody whose dog  died inside its own kennel (they were out for a few hours) because it wore a collar, got trapped due to the collar getting stuck and was stuck in the sun without water within reach.

I understand where you are coming from and having also had that awful experience i can see why you would nt like to leave a collar on at home. I guess there is adanger from any collar worm outside the home of catching on things when they are running off lead in the woods and fields and I really dont know what to say to that one. Having had dogs form 25 years always wering collars its hard to get away from the worry of them slipping out when you are not concentrating
i dont know about some of the other types that have been suggested as to how they will mark her coat I can only try as I suppose each breeds coat is different   

I never leave collars in the home in case of accident ..also as it would damage the coat being a long coated breed.

I agree I am very wary of collars because of that. However I do think leather collars are far safer than fabric. A nylon or webbing collar can easily twist and choke, I'd NEVER leave a dog in one of them. apparently as a small child I managed to get my fingers in the nylon collar of our pup and they nearly lost both my fingers and pup, hence my family is very anti fabric collars.
A leather collar can't twist and would only be a danger as far as another dog getting its jaw caught if it was too loose IMO.

A pup I bred was nearly killed in the same circumstance as you described, thankfully there were 2 people there and one managed to run indoors for a pair of scissors just in time.

After a recent scare when a branch managed to slip between Jade's collar and neck, I purchased one of these

Delivery was really quick and the design seems to do what is says.

Ever since I've had dogs I'd kept collars on them 24/7............until this year when I had a similar frightening incident as Goldmali, came down to unusual sounds early one morning & a youngster had her teeth caught in another dog's collar plus another dog getting between them to 'help'. One of them had pee'd & poo'd herself in fright and there I was stood in all of it struggling with a collar on a dog gasping for breath. Very scary.

I've looked at the breakaway collars but I'd be worried about it coming off as a couple of my dogs would probably have a chew on it.

I carry a pair of scissors in my dog walk bag just in case of accidents with the collar and also to remove brambles which can,sometimes,be very difficult to remove by hand from a long coat. I also had a bad experience some years ago with 2 dogs who were joined together by the mouth with a twisted collar. My long coat dog had his two front legs joined by a long section of bramble which had also attached  to chest hair. I  also carry co-hesive bandage and padding, as 1 of the dogs once emerged from a dip in a pond ,pumping blood from a leg. I had kitchen roll in the rucksack which had to use as padding,poo bag to cover, and cord from  rucksack to hold in place. We were on the downs, a very long way from car and vet.
I know the post is about collars so hope will be forgiven for adding on the other bits.

It's a risk assessment.

I have for the first time had two of mine get caught up while playing, (mother and pup), there are dangers in wearing one and not.

With my breed once they have their coats the collars are deep in their ruffs and rarely a problem, and with half checks usually if rough playing if someone does grab a collar it is pulled over the head.  When dead out of coat I have occasionally had them step into the collar with one paw.  They stand there or walk over to me to be rescued, fortunately they don't tend to be panicky.

If I had not been able to lift pup up to release tension, and lift off canines then I had scissors to do it.  I suspect as the pup hadn't much coat on her neck is why it happened. 

Fortunately apart from the pup squawking as soon as I laid hands on them they calmed down for me to rescue them.  I had my hand in Mum's mouth and as soon as she realised she stopped sawing to get it off.

WolfieStruppi, I wouldn't worry about the collar coming off in play, it doesn't pull apart that easily. My girl plays really rough with my friends two and I have never had the collar spring free. I think it would take quite a twist or pull to seperate it.

When I ordered it I had visions of it coming off at the slightest tug as she spends a lot of time dashing through undergrowth and brambles, but we haven't managed to lose it yet.

How do you prevent it from breaking when your dog pulls suddenly on lead, or more importantly from breaking when you grab them by the collar in case of a dash for an open door (the main reason mine wear collars)?

I had alook at it online it appears that when you have the dog on lead you clip the lead through two d rings which holds the breakaway bit together and takes pressure of it. However if you had to grab the collar as you describe I guess it would come off.
I am thinking of staying with collars i cant trust family or dog not to make a rush through an open door if something more interesting happening. The last thing I need is a large gsd followed by a noisy pomx charging across the road to see someone not something that people enjoy not to mention the danger . I will probably go for the martingale type now I understand what one is LOL
