Bernese Mountain Dog's Emotional Reaction to a New Puppy Is Breaking Hearts
Not all dogs love the idea of being a big brother or sister, especially if they're used to being the baby of the family.
For Gus, the Bernese Mountain Dog, losing his older brother and doggy mentor, Walter, has been a difficult change. New puppy Hank is adorable, but his presence isn't exactly Gus' vibe. During the first few interactions, "Gustopher Gusset Potato" isn't afraid to let his true feelings fly!

original sound - Walt, Gus & Hank the Bernese
Just as the post is captioned, Walt is probably "laughing his booty off from doggy heaven," because that's how Walt first treated little Gus when he joined the crew! It's a Bernese Mountain Dog's bittersweet symphony if I've ever seen one, not that little Hank notices or cares just yet.
There's always going to be an adjustment period with any new pets, but this is what Walt would probably call justice for all the puppy things Gus did to annoy him. Ah, sibling life, am I right?

As the designated big brother who didn't ask for the title, Gus is coming along in his own way. Getting used to all that puppy energy is a lot, but at least now, maybe he can understand why Walt would get a little snippy when all Gus wanted to do was play all day!
Plus, the two of them together are the cuteness that we all need to kick off the week!

Easy Ways To Help Your Dog Adjust to a New Puppy
To give a new puppy the best start without sacrificing the resident older pup's quality of life, experts suggest doing a gradual introduction where each dog has their own separate space to retreat to when overwhelmed, as well as separate food and water bowls, beds, and anything else that could become a territorial issue.
When they're calm, reward them consistently and be sure the older pooch has places to escape where the puppy can't get to them if they're tired of all the shenanigans. Likewise, dedicated one-on-one time goes a long way in reassuring the first baby that they're still just as important.
With all these changes, routines are even more important than ever to establish expectations and keep anxiety low (for them and you!). Above all else, be patient. Things may not be great right away, but given time, they'll be friends eventually (hopefully!).
