Adopted this cutie have no idea what he is? Any suggestions? He's 4 months 8lbs?

I can see some Beagle and maybe also some terrier as well. Cute dog!

I agree with the other answers, definitely some Beagle in there and some type of Terrier.

terrier mix... probably Jack Russell.. looks like maybe mixed with something houndish.. maybe beagle?

Just by the picture, I was going to suggest that there's some Beagle in him, perhaps Beagle/Jack Russell Terrier. The problem is that I would think that mix would weigh more than 8 lbs. at 4 months old.
