Well not just our new pup

Our new pup came home yesterday a 71/2 week old male and was introduced to our 21 month old male outside older dog sniffed him all over tail wagging pup was fine not a squeak
Brought them into the house older dog first and put pup down on the floor in sitting room with older dog, older dog immediately turned him over and growled at him we expected this as knew older dog would want to show the pup who was boss
But still everytime the pup ventures out his crate out male is all over him turning him over and sniffing his bits growling and mouthing at him, sometimes pup runs into a corner and older dog traps him there not bitting him but of course mouthing and growling trying to dominate him but now pup is starting to fight back growling and barking at him and trying to bat him away with his paws

Is this normal, should we let it carry on? If not what can we do?

No, this is not normal.  If you don't prevent it you will have 2 dysfunctional dogs.  It is not necessary for an adult dog to "show a puppy who is boss".  A puppy knows it is just a little puppy and an adult dog can tell by the smell of it that it's just a little puppy.  There's no need for physical domineering.

Keep them separate and give them space. 

i keep my dog away from pups because i know he would want to physically domineer them, why are some dogs like this, and can it be stopped?

I think it is hard to say morgan, especially without seeing it, and it is probably different for various dogs.

What the OP described here sounds to me like the dog almost isn't sure what the puppy is - is it a prey animal - is it a toy to play with etc etc - he sounds very unsure of it and of how he should treat it.  To me, personally, I'd say that was a socialisation issue since he doesn't know how to correctly identify it and/or treat it once he's identified it.  However, I was trying to avoid mentioning the S word for fear it set off another socialisation debate!

One thing's for sure, if it isn't stopped the pup will copy the behaviour as he'll grow up thinking this is the way to behave :(

Personally, I think maybe they need to be in separate rooms but able to see one another, baby-gates are marvellous for this :)  ( I put wire mesh accross the gate to prevent pups just walking thru ;) )  It will give the older dog the chance to observe and sniff the pup (if he wants) without being able to hurt or frighten him ;)  and without being pestered by a puppy he may well be jealous of at the moment.  After all, this little one has invaded his territory and is more than likely having a lot of attention ;)

If you take things slowly now, hopefully they'll get on better later ;)

Im with onetwothree here, thats not normal.

Normal adult male behaviour would be general disinterest in the puppy unless it invades his space. Then some will ignore, somew ill get up and move and if it continues reasonable dogs will reprimand with a growl and possibly an air snap.

This is all relative to how confident the adult dog is with pups, but even one who hasnt seen a pup before should purely be wary and want to remove himself, NOT dominate a tiny, non threatening pup - doing that suggests that the adult dog has some serious problems which need sorting out.

Well we`ve had a bit of a break through both are quite happy to be in the same room as each other and have even taken part in a game of tuggy under supervision of course
We know this isnt the end of it but its certianly a step in the right direction we hope

Personally i think toys can be a big issue when a new pup arrives I find that to take all toys away and give supervised play works better with a chewy squeaky toy each that they can swop.
I dont like to give tuggy toys myself as I find they cause mayhem in our house a dog on either end growling can suddenly turn into arguement!.
When we have a new pup we tend to play with the older dog with the toy ie: throwing the ball for her to catch as the pup tends to find thier own amusement and it stops the older dog becoming jealous.
then separate them again eg; putting pup in his crate ...as they do tend to sleep a lot anyway.
Intergrate them slowly over a week or so works for us.

agree wholeheartedly with Roni and 123 I'm afraid.
Cyrus is still young too (for the benefit of those that dont know Sibes, we dont generally consider them to not be adults till 3yrs)
Good luck,constant supervision, plenty of time outs and calm down times,seperation, I know you know never to drop your guard,and you'll reap what you sew now. :)
I sometimes think this scenario is harder (young male and pup) than introducing a pup to an established pack!

Another little update

Have been following your points and will continue to follow them they are having plenty of time outs etc from each other  and are a lot more chilled out with each other so far no more growling and mouthing at each other no backing into corners but older one is still following pup round like a lost sheep :rolleyes:
We hope this is the start of something good

Thank you all so much for your thoughts and ideas and will keep updating you all on how things are going

Sometimes I think this behaviour is because the older dog is so excited by the new puppy that they play too rough.  One of my pups went to a household with an older bitch who was awfully rough.  That same bitch thinks that the puppy (now 14 months old) is her own and absolutely adores him. But it is always good to supervise just in case there are accidents.

Have you made plans about socialising the pup on his own?  So that he learns how to be with dogs other than yours?

Sorry if you have this covered already. :-)

Yup Lillith pup will be going to socialisation and obedience classes as soon as he has finished his course of vaccinations :)

The are getting along quite well together laying next to each other , playing together etc we are still giving them time out etc
