Jrt/lab mix or jrt/greyhound mix?

[Tango]

I was told he was a Lab/Jack Russell Terrier mix and my brother's gf told me he looks more Jack Russell Terrier/Greyhound mix witch would explain why he is so tall.
What do you think?

I don't see Greyhound, he doesn't have the deep chest and narrow stomach like a greyhound does. His build is far more Lab, so I would suggest Lab/JRT is correct, some Labs can be pretty tall.

Those pics don't do him any justice...I need to post more...He does have a deep chest and and narrow stomach...Also he has those brown/gray spots on his pink flesh that Greyhounds have...










This pic is not of my dog BTW...I found this pic on Wiki...But there is a huge resemblance...I guess you have to see my dog in 'person'...Idk...:confused:
