I noticed that there have been a couple people out there who have recently lost their faithful animal companion. I wanted to share my wife and I's story with you. I don't know if it will help at all, but I know hearing other peoples stories helped me for sure.
In 1996 my wife got a chocolate purebred dachshund. She named her Wilma. This dog was the only hound to catch a rabbit, even the two beagles we still have just chase the rabbits around the property (I am talking about jack rabbits and I don't condone hunting, but, if a dog catches an animal, it's a good hunting dog) practically screaming as loud as they can at the rabbits and then wondering where they went wrong. Since I met my wife about 6 years ago, I did not know Wilma until then. I never had a dog to the day they died. My only dog that I had (a blue tick hound dog) I named ol'blue was given away as a punishment for me getting a D in school. I loved that dog and there is a certain song that can play and bring me to teary eyes. Anyways, because I had never had a dog that long, I could not see suffering that Wilma was going through, my wife's parents however could see it and could tell.
This is what I know about Wilma, it did not matter if it was a bear, the biggest meanest looking human, or even if it was a person wielding a weapon, this small animal would NOT back down to anything or anyone when protecting her master/human. This dog was as stubborn about this as she was brave. She was a good dog, the best anyone could hope for. I had so much respect for this dog, that not only did she keep her place on the bed after we were married (I don't like dogs on the bed) but even after she got to the point she couldn't control herself, I would get up, wash the sheets and put her outside without a spanking, I knew she couldn't help it because she was the best traveling dog and house trained dog I ever knew.
My wife's parents noticed she was suffering, and after witnessing her falling off a 1/2 foot drop from the patio at nighttime, I could start to understand. I told my wife that it was her decision so I wouldn't push it, but I could finally see how she was really suffering. Then one day we had to go up town, her dad asked her " is today the day", my wife broke down crying and said yes. We got Wilma and she rode in the back the way up with my wife in the back. My wife was crying and petting her. We got to the kenel and my wife took off her collar and said her good bye while crying. Her dad and I took Wilma up to the door, and it was locked, because it didn't open for another half an hour that day. I was pissed and thought "jeesh, what else does my wife have to put up with. So, we took Wilma back to the car and we took Wilma to the park and just let her run free (well, not being mean, but she didn't run, it was more like her old lady waddle, didn't matter that tail was wagging away while she was smelling everything). Something funny is when Wilma would go to a new place, she would sniff the perimeter of the area she was in, find her borders I guess, but after that half an hour and she made it about a quarter around, she gave up. Then after a half an hour was up, we took Wilma back to the kenel. Even my "ex-military, now railroad engineer had tears in his eyes. We took her in and explained the situation. Then more bad news, they either needed my wife to go in or to call and give her dad permission to surreender Wilma. I told them, "well I am not going to have my wife come in here, but I can call her". With sounds of sobbing coming from the other side of the phone, my wife said yes, he has permission. After we filled out paperwork and paid for the procedure, I put Wilma down, told her thank you, gave her a hug and a pet, and let the lady take her. As Wilma was getting ready to go through the door, she saw the kenels home cat, she started wagging her tail and went after that feline (not going to hurt her, but for sure interested) and that's my last memory of her.
It is not a downer story, because in the end, my wife (although extremely an emotional person) did what she had to do, even for a dog so close to her heart. We have her collar, and every time I think of Wilma, I knew that my wife had gotten lucky because she got one of the best animal companions a person could get. So I empathize and send out my condolences to you all who went through this.
