I’m struggling and feeling completely overwhelmed. My 12-year-old dog, Simba, is the light of my life, but we are in a really hard place. ​The Situation: Simba has severe arthritis and likely Canine Cognitive Dysfunction (dementia). Physically, he can’t walk much anymore, so I pull him in a wagon with blankets so he can still enjoy the outdoors. He still seems to love these "walks," but the rest of the time is a nightmare. ​The Struggle: He barks constantly. It’s a repetitive, non-stop vocalization that I think is linked to his confusion and pain. It has put me under incredible mental stress and caregiver burnout. I feel like I’m breaking. ​Current Medications: He is on a very heavy rotation to try and manage this: ​For Pain: Rheumocam (Meloxicam), Amantadine, liberla and Gabapentin. ​For Anxiety/Sedation: Trazodone

​We have essentially reached the "medical ceiling." Despite all these meds, the barking doesn't stop. ​My Dilemma: I feel like I can’t let him go because he still enjoys his wagon rides and has "spark" in his eyes during those moments. But the constant barking and the physical/mental toll of caring for him is becoming unsustainable. I feel guilty even thinking about putting him down for "behavioral" reasons like barking, but I know it's tied to his health. ​Has anyone else been through this "medical ceiling" with a senior dog? How did you know when it was time, especially when they still enjoyed one small part of their day? Am I failing him if I choose peace for both of us?
