I have pretty much always had a dog, even if they were not mine directly. Call them farm dogs, or shop dogs, but over the years I have had a variety.
First was a Doberman. Amazing dog, very loyal and loved me as a kid. Overly protective, which could be a concern.
Went to Cocker Spaniel. Really fun dog with a great spirit but short on patience for anyone outside the family.
Miniature Schnauzer: I really loved this dog and he was the first animal I can say I ever created a real bond with. I don't think there was a photo of me when I was a kid without his silly moustachio'd face in the pic. If anyone remembers my Rick Hansen story, this was the dog from that story.
German Sheppard: Insanely smart dog. Sometimes I thought maybe she was too smart. She was leary of men and later we learned that the breeders ex would sometimes abuse her dogs. My mom ended up with the dog when my sister graduated and moved in with her husband. The two of them bonded to an extremely high degree. When the dogs hips went at 11 my mom held her and had our vet put her to sleep. My mom was a mess.
Japanese Akita: This one was a 'gift' from a stripper friend who volunteered at the SPCA. It was dropped off to us - a house with 4 guys who only cared about mountaineering, skiing and girls. But the Akita grounded us and fell in with the family and would always be by our side ready for action. A true warrior dog, it would enter a room first, go around it and then put herself between us and the door. She was happiest when all her guys were in the same room and she could guard us. She loved to fight though, and with all the soy boy and dog moms out there who don't listen when I would say "Please keep your dog away from her, she doesn't like them". Eventually she was banned from the city so we moved. She died of old age a few years ago and I miss her constantly. She is buried in the orchard though, and lives on in legendary stories.
Cane Corso: Present dog. Its our 'shop dog' and is growing to become a real fun animal. Hilarious and playful, often silly. He has some Husky in him so has a tendency to be kind of dumb but the Corse has him ready for battle at all times. He pretty much just watches the world from the bay of our shop. He had a hard time not jumping up on strangers which is pretty intimidating to say the least. Our neighbor has a dog kennel and offered to take him for 3 days so she could do some training with him. He ended up jumping her 6' fence which rattled her a bit. But all he did was run off down the farm road to his best buddies house to play. Not even home, which must be some of that Husky again.
He was bit of a handful at around the 10 month age and it made it hard for my son to bond with him due to his excessive jumping. But we taught my son to lay down the law and be an alpha and he stopped jumping almost immediately. Corso's need a strong alpha. During covid my son and the dog became pretty darn good friends to an almost comical level.
So having said all that, I don't think there really are any bad dogs. They are a wonderful addition to any family.
