Updated pics of my dogs and some questions about introducing them to each other

Hi. A few weeks ago I posted about my new Lab/Boxer mix Tiger. He's doing great by the way, here is a pic a few days old, so he's a bit bigger now...



My mom is going to be moving in with me and she is bringing our Rotty, Vino, which I posted about a few months go...



Remember him?

Well now he's 1 year old and he grew... a bit..



I wanted to know if there would be any problems with them living together since they are both males. Vino has been living with another rottweiler who is the dominant dog, if that tells you anything. So what do you guys think?

i am curious too.. i have a new Cane Corso male puppy and i am moving in with my boyfriend bringing my 3 year old male Golden Retriever.
