my boxer collapsed too
Kiwi hi i just read your post from december. I too had the same problem with my boxer this morning, almost exactly the same thing except I saw him collapse, it was after I was walking in the door, he was overly excited, he collapsed, urinated and a few minutes later completely fine, but a bit shell shocked. I called the vet and they said to just watch his behavior for the day and call if anythin unusual occurs. He seemed fine. May I ask what the final diagnosis and prognosis was for your boxer?
oh my boxer is 2 years old
