Despite his loving personality, poor Roderick is no stranger to being bullied by older dogs.
One-year-old Roderick has been placed on the RSPCA's 'extra-special animals' list after being taken into their Tameside and Glossop branch.
The American bulldog crossbreed needs a "special family" with experience with large breeds and who can give him the exercise he needs.
A RSPCA statement reads: "This is Roderick who is, as you can see, a pretty big boy.
"The other dog he lives with doesn't get on with poor Roderick and we have been asked to find him a caring, forever family to call his own.

"Roderick is a lovely natured boy but, because of his past experience living with another dog, we are looking for a home where he can be an only dog, and no cats as we can't guarantee that he is cat safe."
He needs to live in an adult-only home or with children over aged 12 as he could easily knock younger children over.
Roderick needs to live within an "easy travelling distance" to Greater Manchester.
"If you think that this young bouncy lad could be the one for you and your family, we'd love to hear from you," the statement adds.
The RSPCA is urging people to adopt an animal in need rather than turning to breeders when wanting to welcome a pet into their family.
"While it may be easy to find animals on the internet or even spend hundreds on an expensive breeder, you could risk heartache or huge vet's bills if you don't do your homework," a statement reads.
"By adopting and not shopping you'll also feel good for doing good - by giving an animal a second chance at life in a loving home!
"Plus, adopting from us means that you can relax knowing that all our animals are healthy, neutered, vaccinated and microchipped.
"As with all the animals we rehome, we'll pass on the details of their behaviour and veterinary treatment. You'll likely know more about your rescue animal's history than if you were to buy an animal online!
"We've taken the time to get to know each animal as an individual, to understand their likes and dislikes and to prepare them for life in a loving family, which means there are less likely to be nasty surprises when you get home!
"When you adopt a cat or a dog from one of our centres, you'll also get four weeks free pet insurance, which is vital to protect your pet's future as well as your bank balance! There's so much to gain from rescuing an animal in need."
