Couldn't resist weighing in on your doggie....
I have a Jack Russel/Beagle, and I would say there are many
similarities...along with dachsund, I would say rat terrier & beagle?
Mine was a rescue too.... :lol:

I am starting to think there is Jack Russell in there too.
You should see her glide through the air when she runs...like flying!
She loves the running too, and just happy with everything and everybody.
She has, however, learned she can jump the apparently, short fence, hubby put up, so more work for us to do.
Your pets are so cute! :D

They bring much love, funny antics, companionship and a new dynamic to a family!

I do love my kitties, but BC doesn't get too close to Ginger, so, that left Ginger lonely, when I wasn't out there.
Now, she has a happy, friendly buddy, and I do believe, whatever else is in there, def. some Jack Russel Terrier.
She hops like a kangaroo! It's hilarious! What a sweet baby she it :D

She IS a sweetie! I love her little beetly eyebrows! :D
