I have 3 dogs. A German shepherd and caucasian shepherd mix - mainly looks like a German shepherd, just different color. A German shepherd and X mix - looks a lot like a long haired GShep but rolls his tail occasionally.
And a golden retriever that lives inside.
Yes, holy Fur Batman.
Ok, when retriever is regularly brushed (we don't have furminator) then actually no problems. My family managed to get him full of hair lumps, so I been cutting bits and pieces out. Waiting for a hot day to wash him. Now as he spends more time outside he doesnt leave that much hair inside, but otherwise - clean the house in the morning and lumps of hair fly by you in the evening.
The other 2 shed mainly twice a year, they are just starting to really lose their coats, so when they are playing together my yard gets full of dog hair, so I try to brush it out, but both of those dogs really hate the brush getting stuck so problem.
Tbh, almost decided to shave my retriever, as he is all lumpy and too hot with his thick coat.
I play games with Hulk and a fire breathing dragon.. Love it.
