I have a female Staffy/Boxer, she is adopted from the RSPCA and now 6 years old. She has been neutured as she was used for pups, she also had problems with other dogs but seem to out grow it.
I have bought a puppy a Staffy/Mastif and he is 7 months. He is quite boisterous but I believed her calm nature might calm him BUT it would seem his presence has made her more withdrawn, she's gone back to fighting other dogs and her eyes have drooped.
A few days ago she cried, is this normal? Is he making her depressed? What do I do?

What do you mean a few days ago she cried? Like howled for long periods? Dog aggression needs to be cured by lots of work and patience. I also have a staffy boxer rescue who has major inter dog aggression. I took her to obedience classes which helps her gain self esteem as well as puts me in the alpha position.

What do you mean by her eyes are drooped? Can you see the whites and is it red underneath?

She's been to obedience classes, they both have. She's more prone to attack when there bigger, she gets quite nervous. She has mixed well with the pup. He prays on her loving nature and he loves to be the center of attention. I thought she'd be ready for another dog.
When we first got her she didn't bark at all then of course she has sepration anxiety so she started barking when I left her for long periods or I was in eye sight but she couldn't get to me (Behind a gate. Ect.). Lately she's been barking a lot more, whinging. She didn't eat properly for a few weeks but I've got her back into that. It's really just in her face and her behavior. We are moving house to so I suppose she can feel the stress.
I can see the whites yes, there pink really the normal colour. She has been to the vets for it, among other things. She was badly abused and has had many litters. We got her at 2 and a half years and she was already really saggy underneath. I'm having him snipped ASAP, he's old enough now and needs to come down a peg or two.

The best thing I ever did with my Lady was behavior modification. It was protocols for relaxation and deference that saved us. I swear by them. It really helps to sooth an anxious dog. I notice you have visited some of the other dog threads, but if you look through some of the older ones there are some great posts on inter dog aggression. I'll take a look through and post some of the links for you to take a look at. :)

Thank you very much, you've been helpful.
