My Gran used to own a black and white Collie dog but it was killed when it was about 2 by a fox because it got out from the house and was attacked. But I believe that my Gran's house is haunted by her old dog, who is buried outside in the back garden.
My first experience was from when I was ten. I was sat in my Gran's living room, my gran had gone out to the shops so I was left with my cousins, who were outside playing with my brother, and me in the living room with my Grandad. I looked up from what I was doing and looked outside and from where I was sat I could also see the doorway to the kitchen and the dining room. A black figure caught my eye and I looked towards the kitchen door to see the black and white hind quarters of a dog disappear into the kitchen. The back door was open so I thought a dog could've gotten in from outside but my cousins and brother were on the garden right near the back door. I said something along the lines of: "Grandad, where did the black and white dog come from?"
He put the book down and looked exactly towards the kitchen when we heard a loud bang. We went out and he showed me the open bag of old dog litter (they keep it as a sort of memory of the old dog) was on the floor and it's contents were spilled out. It was on the tall shelf that I couldn't reach, neither could my brothers or cousins because they were younger and smaller. My Gran wasn't back from the shops and my Grandad certainly didn't knock it off. He murmured something like: "That dog used to jump up here and knock my tea off." I thought nothing of it and continued as usual.
My second experience was a few months ago. I was sat in the living room again and I was sitting in the chair facing the TV and the large window that looked on the front garden. My Mum, Dad, brother, Gran and Grandad were either sat on the sofa, facing me or on the floor. My Gran was sat next to me and she could only just see the front garden past the TV. We were just talking and I looked up to the garden and there was a black and white dog sat on the lawn watching us in the living room. I was about to speak before it just faded away.
I said "did you see that dog?" and my Gran nodded whereas the rest of the current family stared at me weirdly. The door opened to the living room, but it doesn't usually because my Gran just had her doors refitted to get rid of the draft. My Grandad started muttering again saying things like: "dog's back" "should rest in peace" "he should have left by now". My Gran hushed him and we began talking until about 5 minutes later, something heavy just lifted itself onto my lap, like the weight of a dog and I heard faint panting. It faded away after a bit.
I think my Gran's dog is still around to see us.
