What kind of mix is my rescue pup?!

[Cmericle10]

Hello- I adopted Toby from a rescue as a puppy in January 2016- he was about 18 pounds when I got him and around 3 months old. All they knew was he was some type of hound mix (I saw his mom-i'll post a pic of her as well, she's the one in the pictures with a lot of white fur ) and he would be about 45-50 pounds full grown. Well Toby just hit the 7 month mark and is just over 60 pounds (OOPS!). I've been trying to figure out what he's mixed with and want others opinions (i'm too cheap to do a DNA test...). I'm thinking maybe he's black and tan coonhound with lab? But i'm unsure. Let me know what you think
