I'd agree with that, and that's how our bitch is bred, sire 1st x collie/grey 25", dam 1st x deer/grey 26 1/2". Was thinking she'd level out around the 25" mark, but finished at almost 29", and I'm glad now that she did, never got her for ferreting, lamping and daytime, and her height has been a bonus, she doesn't struggle on anything
