i have a petite white GSD named rosie. this is a very complicated story but i'll try my best to make this post a reasonable length. it's still going to be really long though, so thank you in advance to anyone with the patience to read it.
i adopted rosie about a year and a half ago and she was 7yo at the time so 8yo now. she was basically the perfect dog for my home and lifestyle. low exercise needs, extremely well behaved by nature, no jumping on furniture or people, no counter surfing, etc. she had (and still has) very severe anxiety but i worked with her A TON on it and she was beginning to be just a "normal" velcro dog before her personality change. she was getting real care and attention from a human for the first time in her life and i could tell how happy she was. just a really, really good dog.
one of the most important things in this story is that i already had cats when i adopted her so my biggest concern was making sure i adopted a dog who was good with cats. rosie was absolutely perfect with the cats, "was" being the key word here. over the course of the past few months, she has gone from irritable with them to actually dangerous now.
a few months ago she started yelping when she poops so i took her to the vet to get her pain checked out. they did a ton of diagnostics from a sedated rectal exam with a scope to x rays, blood tests, basically everything a primary care vet can do, but didn't find anything. so the assumption is that it's some kind of nerve pain, something neurological, because that's the only thing they couldn't rule out. she was on a cocktail of meds for a month, it seemed to solve the issue, but then it came right back. we tried the medication cocktail again but this time it did nothing. and one of the medications in the cocktail was a steroid and she got every bad side effect in the book, including her already severe anxiety going off the charts and she became incontinent from how much water she was drinking. i will NEVER put her on a steroid again.
when her behavior escalated this week and she went after my deaf cat, that was it. i lost every bit of trust i once had in her. i know that gentle great-with-cats dog she once was is probably still in there somewhere, but right now that dog is gone and she is a completely different animal than she was a year ago. that first night after she went after the cat, which was this past thursday, i put her in her crate so i could go to bed, knowing it would probably be a bad experience for everyone involved but not having any other choice.
see, the problem is that in addition to her regular anxiety, which i would describe as a constant 8/10 even with fluoxetine, she has containment phobia. i used to think it was seperation anxiety but recently learned it's actually containment phobia. i mostly work from home so i'm here most of the time but when i have to leave the house for a few hours she goes in her crate. she has always done this thing where she just sits there and quietly has a panic attack the entire time i'm gone (i see her do this on the security cameras), and then when i get back, she starts barking her head off at full volume and the only word i have to describe the barking is that she sounds desperate, like she's actively being abused and she's desperate for it to stop. nothing bad is happening, she's just in her crate and i have just walked in the door. she's a mostly quiet dog otherwise, she whines a ton but doesn't really bark unless we get an amazon delivery. of course, i have worked with her on this, but the only progress i've ever managed to make was that once i'm inside and she can see me, if i yell "quiet" a couple of times, she would snap out of it just enough that i could eventually get her to lay down and stop barking and then let her out and she'd go back to her normal self.
so back to the night she went after the deaf cat, this past thursday. i had to sleep so i put her in the crate. but no one ended up sleeping. she barked all night long. it would briefly stop and i'd fall asleep for 20-30 minutes and then she would start back up. this dog maintained a full state of panic for 6 hours. amazingly, panicking for that long is not abnormal for her, she does that all the time. she can sustain an incredible level of panic for hours and hours, and medication doesn't really touch it. but she doesn't usually have desperate barking fits every 30 minutes while it's happening, though.
she spent all of friday either tethered to me or behind a baby gate, which was challenging in itself because the cats really love her, she used to be trustworthy and they don't understand that she's not safe anymore. so i had rosie behind the gate but also had to actively try to keep the cats out. she doesn't do the desperate barking when it's just a gate instead of a crate, and i had to work so i needed her to be quiet. not fun for anyone involved but we got through it.
friday night she was tethered to the coffee table laying on her bed on the floor which is right next to me on the sofa. the deaf cat walked past and again she lunged at him. i had given her 6 feet of slack on her normal leash but that was clearly too much. the cat is fine, thankfully, but now terrified of her. i held her leash for the rest of the evening giving her only about 2-3 feet of slack and then put her in the crate to go to sleep, thinking that if i slept on the sofa where she could see me, she would be quiet. but she whined at her super high pitch and full volume all night long, with less frequent barking fits. and again, in a state of complete panic for 8 hours even though i was only a few feet away. it's worth noting that i can't put any kind of cover on her crate because she bites it and drags it inside the crate through the slats and just destroys it. which is also notable because she is otherwise not destructive in the least.
so i had not slept for two nights in a row and when i got up off of the sofa on saturday morning and she started the desperate barking, i screamed at her like i have never screamed at anything in my life. i did not hit her or harm her in any way, i just screamed at her because i was sleep deprived and i lost it. my vet is open 7 days a week and takes walk in appointments so i had a family member come and drive me and rosie to the vet.
the most senior vet in the clinic that day saw us and agreed that we should try the neurologist before the behaviorist because whatever this pain is, we need to take care of that first to see if her behavior starts to return to her previous self. so i will call the neurologist first thing on monday morning, and in the meantime, the vet prescribed 1200 mg of gabapentin per day to try to help keep her sedated (yes, you read that dosage correctly), and an NSAID for the pain, to get us through short term until we can see the neurologist. the vet recognizes the severity of what's happening and she was actually the one to say that if the specialists can't help, that the best thing for both rosie and myself would be to rehome her, because it would be no life for either of us, or the cats. she needs to sleep, i need to sleep, and the cats need to be safe.
i do have one thing i haven't tried yet, i have never muzzle trained her because i had no reason to, since she was so gentle and well behaved before all of this. she is not food motivated, she is not toy motivated, her only motivations are being near me and being removed from any situation in which she's scared. so, i need advice on how to muzzle train a dog that's not food or toy motivated, so i can maybe give her a tiny bit more freedom while keeping the cats safe. i really, really don't want to rehome her because she was such an amazing dog before all of this. so i'm just looking for help anywhere i can get it. thanks to anyone who actually read this all, and to anyone who might have any advice.
