My coworker lost his eldest dog that he’s had for about 17 years and I know it was heartbreaking for him, but he has a younger dog who is confused in acting strange and I think just heartbroken because she grew up with the other since she was a puppy. My friend keeps trying to figure out ways to, help her heal. She’s just acting so strange and distant. If anyone’s ever gone through this situation, you have any advice. I know he’s heartbroken from the situation but it’s even more heartbreaking to have to figure out how to help a dog who’s just as heartbroken. They’re both dachshunds if that helps any. But if anybody has any advice would be appreciated greatly.
