Can anyone give me advice please?

My 10 wk old puppy is at the biting stage, I can cope with him biting me but he s biting my other dog (4 yr old) hard on the face, ears, throat…my dog is good natured and isn’t telling him off, today he has drawn blood and I’ve had to rush in to rescue him as he was squealing ..I’m finding I’m having to keep them both separate most of the time unless they are eating a chew or the pup is very tired

Is there anything I can do to stop the pup biting him? The pup is also diving on top of him and also worried he lol fall and hurt himself..my older dog is a big boy

Puppies are horrible, little savages, piranhas on legs, as annoying as it is it's all perfectly normal. They learn to control their biting through the reactions of those they bite. This article explains brilliantly how to deal with it when he's biting you, for your older dog you'll find he's already giving the pup feedback, by squealing he's teaching the pup that "ouch, that was too hard" He'll also be giving other subtle signs if you watch, turning his head away, maybe yawning, By keeping pup and older dog apart you might actually be prolonging the problem, older dog becomes so much more appealing if not there to play with all the time.

Did the pup actually break the skin of your older dog or did you just see blood on him? Most likely blood on the other dog after play is puppy losing a tooth.

What breeds are they both? I've had sighthounds and collies my whole life, and always multiple dogs at a time, a new pup is with the adults 24/7 with as little as possible interference from me, they learn as much from the other dogs as they do from me. I completely ignore most dog-dog interactions, when pup gets too OTT the older dogs will tell them off, it's important they (adults) know that they won't get in trouble for that. Baby puppies have 'puppy licence' almost carte blanche to do as they wish, depending on the adults this puppy licence expires at any stage between 3 and 7 months. Adult males can be particularly tolerant/soft, an older female will teach puppy manners much sooner.

Look at this little rat bag pulling the old boys tail, the older dog here is very sweet and tolerant, but he gets pushed too far and tells puppy off

Thank you, I think I’m just worrying too much…I took your advice this morning and let the silliness begin, much chasing, biting etc but my older dog seemed to manage to push him off better than I can, so hopefully the longer time they have together the less interested in the older dog the pup will be

They are golden retrievers and yes the blood was from my older dogs ear

Of course, there has to be some interaction between original dog and puppy BUT because adults don't normally attack a puppy, there may be a point beyond which the older dog has enough, and might attack.  It's up to YOU to supervise their interaction and correct the puppy.   Never the adult.    For this reason, initially they probably should only be together when supervised.   Ditto for feeding and with any toys of your older dog is still into toys.

If you just let this escalate to producing an injury, to either, then you will have a vet bill, and a relationship which may not be easily sorted out.

I've had a lot of dogs, 15 borzoi, many collies, several lurchers, silkens a couple of gsds and I've never had a puppy injured by one of my adults, never had adult dogs that had to be kept separate because of aggression, because they learn their place from other pack members as a pup/juvenile. I've always left them to sort it out themselves.

I have friends who keep pups separate and only allow limited, managed interactions, but these same friends have various dogs that cannot be together as adults. I don't know if their style of upbringing is the problem or if it's simply breed dependant.

Generally the only time I interfere is at feeding time, nobody is allowed to hang around anybody elses bowl until everyone has finished, then they can all swap.

Maybe I've just been lucky, or maybe dogs are better at sorting things out than we give them credit for.

I think this may well have to do with breed and temperaments within breeds.  Over the years, we've had around 19 Bassets and a Whippet, never forget the Whippet and although those puppies we kept from our occasional litters spent their early days separated from the adults, so attacks never happened, it was really only over food that any spats might have happened.   But again as said, I was always there to supervise.

And again - if things get too full on, correct the puppy because once the older dog sees who is in charge, they should settle down together and be buddies.   Hopefully. 

Tbh I’d have to agree with mamabas. It may depend on breed, but it certainly depends on temperament - I’ve had pups as confident as anything who play pretty rough and instigate play with the older dogs which is fine if said older dog is happy to play or happy to correct the dog. But personally I would say it’s not up to the older dog to correct the puppy, certainly if the puppy is getting far too bolshy and nippy, many older dogs won’t correct a puppy ‘enough’ that is being too rough as they see the puppy as a puppy and vulnerable, especially as the behaviour has most likely gotten worse as the puppy continues to do this. Getting more and more rough. I’ve never had a dog over correct and attack a dog but I don’t think it’s helpful for the older dog to feel pushed by the younger pup to *have* to correct.
For instance my youngest is a confident little swine perfect with other dogs but the first year she was a cheeky thing to one of my older girls who didn’t like correcting her and so would bully her if given the chance - now she’s older the older dog actually will correct her and ironically she’ll read that dog the best and stop play immediately when older girlie stops but had I not intervened from early on and kept those two separate at times I think we’d still be struggling with inappropriate behaviour…some dogs just aren’t comfortable correcting and imo shouldn’t be made to by a bullying puppy who’s nipping is getting more strong.
Puppies should only need a little correction, nothing way over the top. Maybe as the pup gets older your dog may have a little pop at it but honestly personally I wouldn’t want my pup to be getting any big corrections at 10 weeks as at 10 weeks I wouldn’t want the pup to be causing anything that warrants a big correction, but that’s just what I prefer and my thoughts.

We manage everything with baby gates and supervision and it does work, I still have to watch the youngster if she’s over tired or come back from a shoot (the adrenaline can make her a bit out and zooming the first 30mins home) but she can be with them all 95% of the time unsupervised without being stupid ha, I trust her my. For context my eldest is 11 and my youngest is 1, multiple ages in between them now. The first year of a puppy especially with other dogs in the house is always a bit more chaotic but I’d rather be more hands on, mealtimes are fine for us but certainly still will give her a chew/raw bones separately still as one 7 year old lab (ofc) has started sneaking her way over to the youngster knowing she takes longer to eat hers and I personally like all the dogs to give each other space when eating chews/raw bones as I think they can be way more value than meals.

I’ve also had pups who will very early on read other dogs very well and are relatively calm for a puppy so with those as you can imagine they need less of my interference and generally they have never been a rough player. I currently have goldens and labs and they’ve not all been the same but it has seemed to be a character thing and how feisty they are with life lol

Puppies learn canine behaviour from adult dogs. Puppies up to the onset of puberty are allowed a massive amount of puppy"licence"
Over the years I have had multiple breeds from large powerful dogs to small toy breeds.

My male dogs have on the whole stayed clear of close interaction indoors with puppies until the are through the pupodile stage, they move out of the way when the nipping goes OTT.

My bitches on the other hand, seem to enjoy the rough housing. Never had any adult of either sex of any breed hurt a puppy.

I had a rescue GSD bitch who had never been socialised as a puppy with other dogs & rarely played with any of my bigger dogs, but adored the toy dogs, allowing them to nip & bite her ears, paws, tail etc The small ones used her as a climbing aid to get on to the sofa, a soft landing pad to divebomb & generally treat like a living stuffed toy, she would roll on her back to encourage interactions. I think she definitely considered them her perpetual puppies.

I believe interfering & drastically restricting adult/puppy interactions, is foolhardy, ensuring that puppies have enforced rest periods & adults have down time is far more important.

One of my puppy's favourite game was to lie in wait for his full sister to run pass & then grab her tail & be dragged along in her wake, his sister even slowed slightly to all him to catch her tail. His sister wouldn't tolerate outside dogs in her space, due to her not being allowed to interact as a pup, but her little brother was encouraged in play by her.
