Lol, like I said, wolfy, I didn't mean to come across as being obtuse, just that the difference, to me, between a 2 month old pulp and a 4 month old pup is pretty obvious.
Well, at 8 weeks or 16 weeks, it certainly shouldn't be sucking on a tit.
And you seriously can't tell the difference between an 8 week or 16 week old pup?!!
Was just gonna say, whippet pups can be extremely 'trying' when they are young. Very feisty and practically non stop.
And I suppose that could easily apply to whippet crosses that take more to the whippet mentality.
