...how far can our 5 month puppy go?

i thought a pup would be self limiting on exercise and if asked to do too much would sit down/look tired

but a bit of research indicates that they don't self limit and too much exercise could be bad for their physical development and lead to problems later in life.

molly is a bedlington terrier - whippet cross, she has been for a few 2 mile jogs (hopefully to no permanent damage) since the weekend.

should we hang fire on this til she's older?

hoping IainR and other dog owning forumites can advise.
