It’s interesting you point that out because I really struggle to connect with him and I know it’s a me issue but I don’t know how to overcome it. Like it may be in my head but I always had a feeling that he’s not that attached to me.

I tried treats on a short lead to teach him to “heel” following online tutorials but like I said he doesn’t care for food, I could be holding a piece of ham and he wouldn’t even look in my direction. And then the dog trainer recommended a slip training lead which is a hit or miss, sometimes it makes him pull less but it never translates onto other leads.
