Dam was a full whippet sire was meant to be a 1/2 cross boxer whippet, looked just like a heavy whippet with a stubbier head... Only go on what they were told, enough running dog in them to serve a purpose anyhow. I always said I couldn't see boxer in your sisters pup, can see it even less in the other pup. Belters though whatever they are, happy healthy looking things.
All dogs look well mate.
We'll never really know gaz, but you said it, happy, healthy and I'll add hungry that's all we can ask for...
