Help please

So the first week with Vinny home has gone well in terms of house breaking and getting into a routine.Obedience wise he can sit and do a bit of a recall. We "think" Roxy is taking it well too but.....

Roxy is 10 months old, very mild tempered. She has had no problem with Vinny (8wks) playing with her toys, nicking her food, climbing in her bed etc. Vinny is extremely outgoing and the last two days their play times (always supervised) seem to get rougher - instigated by him. Roxy is putting him in his place with looks, gentle nibbles and nudges. Vinny on the other hand has already tried to put his paws up on her (wrestling/dominance?), he growls at her, he hangs on to her lip, he bites her and scratches her. He warns her off if she approaches and he is playing with her stuff.

Is he too young to be showing signs of dominance/aggression and just being boisterous? Roxy seems to be playing (her posture is completely relaxed, floppy ears etc). Is it maybe just typical staffie play that gets too much? And when is it time for us to step in? If we do, is it wrong to scoop Vinny up out of the way?

A lot of questions, sorry - Vinny isn't too affectionate and he doesn't seem to want us to cuddle or give him much attention either.

We haven't had 2 dogs before so we're not sure when to get involved or when to realise it's a problem or play time. Any help will be much appreciated!!

PS: Took Roxy to her dogtivites class yesterday and she was all over some woman licking and cuddling and playing. The woman was giggling and said "I thought these were meant to be viscious, but she's so loving." Yay Roxy

Sounds pretty normal to me honestly. They all have different personalities but if Roxy isn't showing signs of fear ect, sounds like play to me. You will most definitely know if it goes past fun and games- it is much more intense and you will come running to break it up. Do they each have a place they can go to have undisturbed alone time? Also, don't leave them alone unattended. I'd tend to not scoop one but train them to leave each other- you can do this by making them drag leads you can quickly grab. However, get cheap ones because they will get chewed to bits! Some dogs like to cuddle more than others. Just personality. Getting used to two dogs is a challenge and having two so young can be more so, but you'll get there!

Never be afraid to ask all the questions you have. We have all been there... and still are at times.

Thank you! Yes, they do each have a place to go off to - Roxy goes off to her kennel and he has a crate, but he prefers to pester Roxy and neither of them are keen on "leave it/no" when interacting so I like the leash idea. We're still getting Vinny used to his collar and Roxy thought that was great to grab hold of yesterday - not so safe.
Thanks again

Yes, you have to work on the collar thing and never leave it on full time. It can just be helpful in supervised situations, which honestly is probably all of the time right now for you. I have lost a few good collars as they do make rather nice "handles."

Sounds like playing. If Roxy is very calm and mild-tempered, you're probably just not used to a puppy that isn't as calm and is more boisterous. They all have different personalities though, and he sounds like he's just being cheeky Roxy will tell him off when she's had enough, but of course if you think she wants to be left alone, by all means step in.

As for the lack of affection, don't worry about that. Loki was the same, we never really cuddled him or anything because he didn't like it, all he wanted to do was play. He wouldn't sit still for more than a minute, you couldn't stroke him much because he'd start biting, etc. But now he's happy sitting next to us and letting us stroke him. In fact, if anyone stops for more than a few seconds, he looks up at you wondering why you've stopped, and if we don't continue, he goes off to someone else he'll probably grow into it. At the moment he probably just wants to play or sleep 24/7.

a good post as we are thinking of another dog. Hopefully they will settle together

Sounds normal to me as well. He is still just a pup and will always want to play and explore his limits

Ben's advice is good , this is just normal play , the paws up gladiator stuff ?? have you not seen my pictures and Tilly was 2 years old. You will get it more from both sides long term because Roxy at 10 months is very much a pup herself too. You should not leave them out of eyesight though , separate when not watching just to be sure as if Roxy is pushed too far at 10 months she isn't really old enough to understand what is going too far

As above great advise already given.

When I got my pup Tank he wouldn't leave Diesel alone he'd bite n nibble her bark etc hang off her ears neck lips etc but it was only playful.

I'd pop Tank into his crate a few times a day to give them both a bit if peace and it helped get Tank used to his crate.

It's basically like supervising 2 kids n playin referee at the same time lol.

Thanks all! Vinny does exactly that : hanging of Roxy's lips etc.
We supervise them at all times when not separated. They are separated by baby gates so they even tend to lie on either side playing through the gate. It's so hard to imagine we'll get to a point where they won't need supervision. all your advise has been great, though. Thank you!
