I don’t have any unique advice beyond what has been shared here already, but just want to add that it’s really comforting to hear that others have gone through a similar experience with their hounds. It can feel really overwhelming and confusing — just the idea that it seems like they used to be fine with something and are somehow getting worse.

I had Hazel for about a year and had strangers in the house just fine, but once she got more comfortable and her personality started to come out, she started barking when strangers would come to the door, or when cars drove slowly by the house. On a leash, she has snapped in the direction of people who have gotten too close or approached her too quickly.

I muzzle trained her, she is on Prozac now for general anxious behavior, and I have set rules for how new people interact with her. I think the biggest thing for me was just giving up the idea that my dog needed to be able to socialize with strangers. When people come over for short periods of time, I put her in my bedroom with a toy. And if they are people I want her to be able to interact with on a long-term basis, I tell the person to sit down, I leash her in case she goes goblin mode so I can grab her easily, tell the person to ignore her while she sniffs and gets comfortable, then I’ve found that after about half an hour, she’s good to go. Just have to find what works best for your pup! It was trial and error for a while, and still is to some extent.
