Will suddenly pulling leash backward hurt my dogs neck?

Yesterday I was putting on this flexi(retractable) leash on my 10 week old doberman so that she can have more freedom while trying to get him use to the collar and leash on. I only uses it in my backyard, out on walks I use a short leash. But then last night, she was extremely hyper and keeps running around crazy, I accidentally clicked the retract button while she was running forward in a high speed, and that pulled her back suddenly and made her fall backward on the grass, she doesn't seem to be hurt and keeps on playing and eating fine, but I am just worried if it could cause any internal damage to her neck or something ?I'm now planning to use it again, I'll just use normal leash from now on. I never used the flexi leash before, but since I want to give her some freedom to roam around backyard I thought I might aswell try it, looks like I'm wrong... Yeah she's eating, drinking and playing fine, being her normal self.I mean I'm not planning to use it again, not now planning to use it again lol

yess

Does someone putting something around your neck and pulling it hurt? Yes. This happens a lot to owners. I don't think anything bad will happen, but if you want to be sure get a harness. I prefer the harness to the collar because you have more control and it doesn't really hurt them as long as you don't pull too hard. But of course still have the collar just in case your dog gets loose.

If she is eating, drinking, barking, and playing the same I wouldn't worry too much, this is one of the reasons why I hate retractable leads, they are very dangerous even in your own backyard, I had a friend almost lose her eye because it broke and snapped back, I also got plenty of burns from it, I would teach the dog recall off leash, much safer IMO.

If you start to make a habit of it, then yes, you can hurt your dog. Just doing it once on a retractable leash is unlikely to cause any seriously injury, they're designed to be more gentle than say if you suddenly yanked on a normal leash. Try not to do it too often as it can lead to behavioural problems if you pull hard all the time, but a gentle tug now and then when they start to pull is alright.

yes

Yes i'm sure it just stunned her a bit. Dogs are a lot tougher than people tend to make out, i'm sure she hasn't broke her back or anything.A good thing is a harness, I much prefer them and I feel I have more control over the dog if the leash is attached to its back area rather than neck.

Yes and also in some cases no. If you hear your dog chocking that tells you not to pull as hard.Yes it does and it can cause serious damage if the dog is wearing a dog collar and not a dog harness. Dog harnesses prevent damage to a dog's neck and specific types of dog harnesses are designed to prevent pulling - anti-pull harnesses are used to stop a dog pulling, along with training....!!

Yes any type of flexi lead can cause neck damage if the dog is sharply pulled up with a hard stop. If you see a problem in the way she is holding her neck, any stiffness or awkwardness in movement or sign of discomfort, take her to the vet for an examination.I suggest you purchase a long leather training lead, which is a superior product for many reasons including the unlike a flexi which is a large lump in the hand, the leather loop is soft and you can “feel” the connection to the collar, still have control over the dog in open spaces when teaching a recall, but no sudden jolts as the human lets the length out and reel it in and you do not have to rely on the flexi brake mechanism working when you need it to.At 10 weeks a Doberman puppy will get all the exercise it needs from playing in the back yard, with off property exercise for training and socialisation and not more than 10 minutes at any one time. It is a medium size breed prone to hip and stifle problems and over exercise when young bones and joints are developing can cause long term damage in the adult.I use the five minute for every month of life as a guide until a Doberman is one year old and then build up the dog’s stamina as it matures and muscle mass increases.If you want to tire the puppy take it out into the garden and work its mind with training, throwing in a bit of tracking and chase a frisbee or ball which is useful to teaching recall and give – the dog dropping the object when the game is over or to continue it. Mix up the training with games and keep what you are doing fun and no more than five minutes as a puppy has a short attention span. Use a high value food resource or toy – whatever motivates your puppy to focus on you and get her is the right position by your side on a six foot leather lead and gradually increase how far she is expected to walk by your side to earn a reward.Allow the puppy time outside off leash (if the back yard is fenced) to zoom around and be silly playing with its toys.It is normal for a Doberman puppy to have explosive burst of energy and be into everything and love to chase and pounce on moving objects and then sleep hard to get ready to start again.
