Sorry to read you are having problems with your puppy - can you share the advice the breeder has given at all?

It is possible for puppies to be aggressive, but often puppy biteyness is wrongly seen as aggressiveness (but not saying that is the case here).

I would definitely look into the diet.
It is possibile for some puppies and dogs to become aggressive, it seems, if they are "intolerant" to part of the food. For example a puppy in rescue was given a change of diet (it was the only thing that altered) and became quite aggressive, but when the diet was changed, the pup became calmer and more easily relaxed. It's not always obvious it is the food, though.

I would have thought true aggression in a puppy this young will be genetic or due to illness... but in most cases its usually down to over exuberance.

Thinking about it, I do recall a Rotti pup that was PTS at 5 mths old..due to his aggression, and that was serious aggression..

Turned out though his sire was known for aggression.

I think to many people (we see it here all the time) think a biting pup is aggressive, and most of the time, its down to not being tuned into a puppies behaviour.

I am glad the poster has spoken to one of the breeders, lets hope they can help sort his behaviour out.

I would guess (unless proved the pup is aggressive) the puppy has simply got to big for his own good, play biting has simply got out of control.

I knew someone with a young Boxer who said his dog was out to get him, (pup was 6 mths old) because he (pup) would push the owner into the hedges and bite at the lead

i think from the general consensus on here, its probably a very boisterous puppy, that need to be taken in hand to learn a few manners.

I wonder if this was the cause of your problem, that puppy was tired (as you said) and he was simply resisting being made to walk home.

Sometimes you will see an otherwise biddable dog reacting in a manner not usual to them, in situations of stress.

If you have not seen any level of the same behaviour before now, then maybe it was down to the situation . and he was simply tired!

Can I just ask, how would you take a boisterous puppy "in hand"?

What would a mummy dog do with a puppy like this?

Is it possible to replicate what the mother would do?

Sorry you can tell I have had very little experience with puppies can't you.

what judgemental advice

have a trailing line on him if u think he will act like that again....no need to grab collars or react to him.

also i asked about treats and diet for the reason wysiwig mentioned

or didnt want to go home

flea isnt a 'mummy' dog but a 'nanny dog'.... he would ignore ignore ignore...then muzzle hold if pushed....something i wouldnt replicate lol.(the muzzle hold)

By setting some rules in place and and act on them

I would assess the situation, do some research on puppy /dog behaviour (if needed) and work out a regime and rules to work by.

Thank you, I do wonder if that was the case, the breeder also felt it was him testing boundaries and advised nipping it in the bud - she thought I'd handled it correctly, which was reassuring after some of the replies I had here that made me feel I'd made an enormous error.

He's never acted anywhere like that before, hence me trying to find out if there was something wrong, he's normally an extremely placid, friendly, loving pup, even during his little nippy half hours if we say "Ow" loudly, the next time he'll still nip, but will be gentler - always very reactive to us.

I can only assume you've posted that to be inflammatory.

Nice. Oh and extremely non-judgemental.
