Gilbert sure looks 100% EB to me, look at my avatar picture of Vegas, he is also on the taller side. from shoulder blade to feet is 17 inches. He sure is a handsome boy!
I think he is probably English, only by pedigree could you be certain. Depending on the breeding line its sometimes almost impossible to tell by looks alone
Looks like English to me, my Brutus was and had longer legs, my new adoptee,
Cami is English but very low to the ground...they both weigh about 65 lbs.
