Anyone speak Romanian?

My dad was born in Romania and I was wondering about phrases he says. I know very little Romanian but my dad generally tells what he is saying if I ask. However, no matter how much I beg, he will not teach me curse words even though I am a grown man. All I know is that they have something to do with a dog. I can only spell these phonetically: "Peez da mutteeh the caine" and "Foo-tus verro mutteeh the caine" I hope someone can finally tell me what these phrases mean.
