My 3-month-old puppy is a Cane Corso cross Griffon. His house training is spot on, so no complaints there, but we have a pretty major issue. He is very often aggressive and bites to the point of drawing blood; it’s quite hard to tell when he’s playing and when he’s not. We’ve tried everything: shouting ‘ouch!’ when he bites, ignoring him, giving him a toy, but nothing seems to work! We end up putting him in a separate room until he calms down, but that only works for a little while. On top of that, he barks at us for no reason. It’s a really unpleasant situation and I’d appreciate any advice or ideas you might have!
Thanks in advance.

I doubt it’s aggression; I’d say it’s more likely down to puppy excitement. He needs a consistent routine—flexible but clear.
What does his daily routine look like indoors and outdoors? Do his walks involve meeting other puppies and dogs off-lead?
By finding the right balance between exercise and rest, he’ll settle more easily, provided you stay consistent with your interactions (e.g. when it’s ‘his time’, he gets attention, but otherwise he doesn't, so he learns to occupy himself or rest). At that age, mine had her toilet breaks, socialising with other pups/dogs, and several short play sessions with me indoors (on/off games are great for gradually building self-control), and plenty of quiet cuddle time, of course.
Personally, I don’t think isolating him is the best solution: you aren’t there to help him calm down (I reckon ignoring him in the same room teaches him much more), it can increase frustration and energy levels, and you can’t exactly isolate him when you’re out and about. That said, I know others have used that method successfully, so it really depends on the person and the dog.
Anyway, I hope that helps. Learn to understand his energy, how to burn it off and how to channel it gently, and you’ll avoid plenty of issues in the future.
@Turdusmerula, initially, I wouldn't use play to reinforce calmness because play is an activity, meaning you're putting the dog back into a high-arousal state which could set them up to fail. However, once the puppy has mastered impulse control, you can reinforce it with a short play session that always ends with a "sit" – in this case, you're also strengthening the bond between the dog and the owner.
Since the goal is as much about redirecting the puppy to its toy as it is about interaction with the owner, I think both methods have their merits...
It’s up to the OP to give them both a go 😉
Turdusmerula, to start with, I wouldn't use play to reinforce calmness because play is an activity, which means you're putting the dog back into an active state that could set them up to fail. However, once the puppy has mastered their impulse control, you can reward them with a short game that always ends with a 'sit'. In this case, you’re also strengthening the bond between the dog and the owner.
The advice from @Jcne and @Docline matches a little experience I had with a 4-month-old female pup who, like all puppies, tended to get overexcited easily.
She would jump up at me and bite my clothes.
Teaching her to sit was a huge help — a puppy that young is perfectly capable of picking up that command quite quickly. Once she sits, reward her with a short play session using one of her toys. It's not enough to just hand her a toy; you need to actually interact with her, let her burn off some steam with it, so she associates it with an outlet that's allowed.
If she grabs your hands or clothes during play, stop everything immediately. She needs to learn to respect your personal space. These sessions will help you stay in control and teach her to "calm down" before she gets a response to what she's asking for.
Walks should also give her the chance to meet those older, well-mannered dogs that @Docline mentioned. They'll teach her that there are boundaries not to be crossed, and indirectly they'll be a massive help — not to mention that all that activity will tire her out, so she'll be far less likely to go full T-Rex mode once she's back home.
But honestly, there's nothing unusual about this puppy at all — it's just a phase that every puppy goes through when all they have is their mouth to explore and engage with the world around them.
At three months old, your puppy can’t be aggressive; at most, they might be reactive, though that doesn't seem to be the case from what you’ve described. Using a time-out can be a solution, but only if it doesn't last longer than a minute or two. Anything more than that is counter-productive, as the pup won't be able to link the punishment to the specific action that caused it. If your puppy is drawing blood, it means they haven't learned bite inhibition on human skin yet, and it’s likely because they’re over-excited. Simply stopping them from biting won't solve the root of the problem, and putting up with that kind of biting is unacceptable. There are ways to sort this out. Your puppy barking at you is also unacceptable, as they’re trying to assert control. The first thing to do when they do this is to give a loud, sharp "eh!" to break the cycle of the behaviour, then immediately redirect them to another behaviour—ideally asking them to sit—wait a few seconds, and then praise your puppy for being calm. If your puppy doesn't know how to sit yet, that’s the very first thing you need to teach them. Your puppy is simply going through an excessive "consummatory phase" which you can and must manage using the most effective commands: the "sit" or "down". These will help you reach the "extinction phase" much faster.
All puppies mouth, all puppies NEED loads of play, and no puppy this age is aggressive.
Some just get far too hyper because they aren't being properly exercised, or because they're an only dog.
A puppy needs plenty of daily socialisation with other dogs, including well-balanced ones that can put them in their place and teach them how to keep their excitement levels in check.
You shouldn't give the puppy any attention when they’re wound up; you need to wait for them to be calm before feeding, stroking, or playing with them. You mustn't give them attention the second they demand it, but since it’s an essential need, wait a few minutes and then invite them to join in an activity on your own terms.
