i have a mini dash , full on purebred , and she is so spastic , she doesnt understand sit or any command. she is very small , but still on the large end of mini.
she has recently had a herniated disk in her neck repaired , only to have her back degenerate. she has always been fed premium food , vets every 6 months , etc. well taken care of , never hunted or allowed to jump , and still have problems..
we had 3 others from the litter as well , but ended up finding them all homes when they were about 2. if i were you , i would look at full size , ant try to find one that is a slight mutt. the purebreds are known for being constantly spastic.
i will say one thing , when she goes in the back yard , you know right where the bunnies squirrels and mice have ran. she even went down a mole hole once and dug it out. so as far as that goes , they are very smart dogs , but the health and temperament were way off for me.
if youre intent on a dash , like i said try to find one bred for temperament , or get a mild mutt mix. all the dash mutts i have seen had a much calmer sense , and actually took direction.
just for reference , i am currently looking for a rescue brittany. i couldnt see the point in spending the money on a dog that cant even get in the car or on the couch...
good luck , keep us updted./
