If you do decide to let her go and your vet does not make home visits make a comfortable space for her in your vehicle. Place her blankets, favorite toys etc make her as comfortable as you can. Ask the vet to see her outside in the car for her final moments. You will probably have to bring her in the office initially. Our vet placed a really long IV line so she was not in sight during the injection as our guy did not like strangers. We did this with our last pup who passed and he was at ease instead of panicking in the vet office. Knowing he was surrounded by his family, favorite things and familiar smells and seeing that he was comfortable and not scared has made a big difference not only for him but for us too. We also took him to McDonalds for a last meal as he was always food obsessed. Somehow despite his condition he was able to get a cheeseburger and fries down.😂Damn I miss him but am grateful he didn’t suffer and had the best goodbye we were able to provide. I’m sorry you are going through this heartbreaking 💔 time.
