My beautiful English Springer Spaniel Duchess seemed in excellent health when I adopted her. She was full grown, spayed and approximately 4 years old when I adopted her from our local shelter. She had been turned in by her previous owner because his wife did not like her. She was due for her yearly vaccinations when I adopted her and also was seen for her initial exam, which she passed with flying colors. However, she developed a small lump in the area where she got her vaccinations...along the lower neck, scruff area slightly to the left side. She didn't seem to feel too well for the first couple of days after her shots...nothing serious, just kind of quiet and "off". She improved and continued being normal for the next year, until her next check up and vaccinations. She again had a lump and was not feeling very well for a couple of days, then improved. A few months later, she began limping on and off and seemed to be sore in the shoulder area of her front left leg. After treating it according to our home/vet books, with little improvement, I made another appointment with a vet to see her. We went to my parents' vet as ours was retiring and we wanted to get Duchess introduced to a new vet before it was time for her vaccinations again. I told the vet of the problems she had with her vaccinations and she remarked that it was really common for dogs to have mild reactions to the vaccinations, especially at the injection site. She then proceeded to examine Duchess overall, and then her leg and shoulder in particular. Duchess had some numb areas on her leg, which were unusual, and after just a few minutes of testing, the Dr. diagnosed Duchess with terminal cancer. She was given a 1 day to 1 year prognosis. I began researching the type of cancer she had on-line and found that it has increased exponentially in dogs over the last few years and SOME experts thought it is linked to over-vaccination of dogs, especially when the primary site corresponds to the initial site of the cancer. That was Duchess' case. Her initial tumor and nerve disorder site was the same lower neck, scruff portion of her shoulders slightly to the left side. After a great deal of reading, I took Duchess off commercial dog food, which decreased the size and number of her tumors almost immediately. With the addition of supplementation of vitamins, minerals and amino acids, and home made meals with people grade lean turkey and beef, organic oats and brown rice and vegetables, Duchess improved and did well for two years. About 2 to 3 months after her second year, her symptoms began showing up again, and we lost her, at home at 3 years and 4 months of her illness. After her diagnosis, she never had another vaccination and even her pain medication she was prescribed for the cancer was discontinued because of side effects. We were blessed that she actually had little pain, which was unusual for her condition and even toward the end, only needed baby aspirin for discomfort. She was able to stay home, with little pain and little disability to the end and died literally in our arms. Her vet assured us that her cancer was not caused by the vaccinations, but most likely by other environmental causes. I don't believe that....the location and onset of her cancer was the exact site of her vaccinations. We have since grieved Duchess and gone on to adopt two rescue Poochon/Bichpoo dogs. They are young and received vaccinations at the rescue before we adopted them. Our new veterinarian has agreed to titer test the dogs before vaccinations. I hope this will ensure our new little furkids will be safe from any form of vaccinosis. I still miss Duchess and grieve because I believe she died too young and that we helped cause her death by having her vaccinated as required, rather than learning about the dangers of over-vaccination. I hope titer testing before vaccinating becomes routine with all vets, for the well-being of our pets. I hope Duchess' story will cause some furkid lovers to look into titer testing for their furkids....it might save their lives.
