Well I took him to let's at home this mor I g to get him scanned and they said he's a puffer so most of you were right! 
I assumed he'd have a flat face if there was put in him but the beagle must've erased that, your right though the eyes and the tail were a giveaway lol.
I actually found him wandering around on the road last night and I nearly ran him over
then the car behind me did too so I got him and rang the number on his tag but it was switched off, so I bought him home.
I took him to let's at home thinking I could take him back to where his chip is addressed to but they said legally they couldn't tell me so I had to leave him there, they said if no one claims him in 48 hours we can claim him or he can go to a rescue
