How to handle a dog with intense guarding instincts

“My almost 2 year old Bernese mountain dog has been acting up since we brought our 5 month old daughter home.”source ↗

“When I approached him he growled the most intense growl, and hovered in front of it. I didn’t feel safe getting it away from him”source ↗

“He growled at me, and (after apologizing to him) when I tried to continue to move past him, he growled again and this time kinda lunged to bite me?”source ↗

“But I’m concerned. He has been very jealous of the attention we give our daughter, especially when we baby talk with her.”source ↗

“He immediately began to growl at me so I backed up. I tried distracting him with treats and directed him off the bed. He took the treat and before I could even go to clean the bed, he ran back up and continued to growl over the throw up.”source ↗

“Owner warned me the guarding instinct is no joke, like guest announces themselves 15 minutes before arriving or dog decides they are intruder.”source ↗

“If you can handle strong will and endless brushing seems worth it, but I ended up with lazier breed myself.”source ↗

“when it’s bedtime the rescue dog will show her teeth and get mad if the other dog gets close to her”source ↗

“it happens only at night time and not often but I can say it’s happened at least 3 times total”source ↗

“it’s only at night when the aggression starts.”source ↗

“She is a really sweet and good dog, but so anxious and I just don't know what to do to help her.”source ↗

“The bigger issue is that she completely looses it with big dogs. She litterally has a psychosis and is unreachable.”source ↗

“Whenever we tell her off she is so ashamed. And I hate to admit it, but we do tell her off loudly and harshly.”source ↗

“when they’re in the area, kind of grass and stuff like that, he runs along the fence and when they come close to the fence, he can growl a bit”source ↗

“This has led them to text me to tell me that I need to put my dog inside or restrain him in the yard because they are too scared of him.”source ↗

“the older dog is extremely resource-aggressive over toys and bones. He has already lunged at the puppy once, causing a wound on the puppy's ear.”source ↗

“Yesterday, even though they were eating bones under supervision, he managed to nip the puppy when it approached him while he had a bone in his mouth.”source ↗

“The older dog is very keen on playing with his toys, so if that always leads to a fight, daily life is going to be difficult—and even dangerous.”source ↗

“Today, he snapped at my hand when I tried to take a treat away without warning.”source ↗

“it makes me nervous because he’s already a very shy and nervous dog and I don’t want his timidness to turn into aggression when he’s older.”source ↗

“He also tends to be very unhappy when my older dog gets near his crate (which he loves).”source ↗

“the random items thing is tough cause you cant really predict what's gonna be high value that day.”source ↗

“I have 14 week old puppy who goes crazy only over cheese. If he has cheese, he will growl, bark and likely bite.”source ↗

“I‘m so anxious. Crying. Depressed. This is my first dog and this is also not his only problem.”source ↗

“And I‘m close to giving up. So if anyone can give some input on how they trained and how it turned out, I‘d be very grateful.”source ↗

“My older dog (6yo) and new puppy (6month old) both tend to resource guard food. I feed my puppy in his crate and if my older dog gets close he’ll growl.”source ↗

“We feed the dogs separately but occasionally if one finishes a bone before the other they tend to “check in” which the other doesn’t like. My question is how do you get down to the root of it and fix it? And does it typically last forever?”source ↗

“Our Goldendoodle puppy growls and snaps at us when we come near anything that he’s decided is his (incl. the groceries and clothing items).”source ↗
