Tyson, has in the last 6 week had a very sore paw. He has been tested for all known Doggie disease and is free of any. It is believed he had a extreme reaction to a insect bite. Tyson has had more test done then most stud dogs. All test have came back clear. He is just a very healthy 7 year old dog with an wonderful personality. I am letting you all know to be mindful of insects in your home and garden as Boxers are renowned to suffer insect allergies of all types. Tyson is now full recovered and as you can imagine vet fees haven't been cheap.
