Hi! I have a 3 year old sheltie and am wondering if his coat will ever grow more? is it possible for their coats to take a little longer to fully grow in? I love him regardless, but it is a little disappointing when i’ve been expecting all this time for him to get this nice long coat that goes down to his legs. I know that a lot of the pictures on the internet are of dogs that are propably shown in contests, but I have seen plenty of pet shelties in person that have a nice full long sheltie coat, and my boy has nothing close to that. Thanks for any help!
