Had a Manchester terrier x whippet years ago she was a good little mooching dog.
Caught no end of rabbits, phesants, partridge, sqirrells, rats a few hares and rolled the odd fox (she couldn't do em single but she wasn't a fox dog so no sleep lost).
Her take off speed was like lightning but would fade after 100 or so yards.
Would love another like her just for bushing and mooching about.
She died 4 years back from a stroke aged 14.
