Make him go away!

OMG! When we got home last night there was a beagle on our front porch. He won't leave! Has a tracking collar and a name and number on it, but no phone number. I have tried calling the vets offices to ask if anyone had called looking for their dog. No luck there. He is driving my dogs insane and the poor cats are terrified. Every time they move he starts chasing them and bellowing. He needs to go HOME! NOW!
