Is this a pure Rough collie?
Hi so my mom gave me a dog and the dog was unfortunately form a byb. But the person we bought my puppy from claims that the mom is a rough collie. But imo she don’t look like one.
I came to this subreddit to ask you guys because I don’t know so much about rough collies.
(The pictures is not my dog it’s the mother to my puppy)
My puppy is an rough collie/aussie/ flat coated retriver mix. He is 6 months old now
Edit: after these comments I really got interested about what breeds he can have in his dna. Would be cool to know.
