I have two Mastiffs , & use to have a Dane
I can’t do puke, I’m a hunter and process all my own meat, but can’t do puke.
As for the shit, get him off of the bag of garbage , and find a raw food diet, it will cut the size in half , n they will be hard n turn white in a couple days .
My male is a rescue, and is bat shit crazy, I’m sure he would have been put down if I didn’t get him. Ever have a 70kg dog laying on your chest , and you to move an scare him then he’s growling with his teeth out inches from your face? Has very bad fear aggression, but we deal with it, he’s part of the family now.
I have more experience with dealing with giant breed dogs then growing,
( and ya I know , most would have kicked his ass etc etc , put him down etc etc , every case is diff, and he can’t help that he had a very bad start)
My other one I had from a puppy and is a teddy bear .
