Species ID for extinct mammal repaint project

[Saarlooswolfhound]

I had a really hard time trying to decide what category to put this in... Admins, if it would fit better elsewhere please feel free to relocate it.

Anyhow, I have a couple of figures that I am interested in custom painting as I don't feel like they accurately fit any extant animal well enough to keep as is. I am interested in turning these into prehistoric themed species if they can fit the characteristics of one or another (I think they are close enough). However, despite all my research and excitement, I either can't find a species that fits well enough or I just can't settle on one or the other... thus I have decided to crowd source.

Any thoughts?


The top 2 are my prime focus, but the bottom 2 I think might work for this project idea also.

I know that really I can repaint them however I like since we don't know the coloration or patterns they actually had. But it helps to have an ID either for inspiration from paleoart or to find a modern/extant homology to work from.

Any and all thoughts are welcome!

I'm not too familiar with Mesozoic mammals, but I reckon the grey one can pass off as a Dildelphodon.

The mustelid could be Enhydriodon

Thank you both for your suggestions!
