Does this look like a good purebred rottweiler to you he was dirty at the time of the pictures if so does he look healthy?
Yes, judging from those photos I’d say he’s purebred, a nice looking dog overall. Good pigment and eyes, and a European body type and head.
Health is a more difficult call as many conditions can’t be seen from the outside. He has some discharge around the eyes, but that’s not unusual and it looks as though it may have been hot or he was pretty stressed as he’s a bit ‘slobbery’. Again, pretty normal in those situations.
He’s not in the best shape I’ve ever seen in terms of grooming etc., but he looks okay overall. However, it’s very difficult to judge from photos and I could be wrong on both counts!
