I am heart broken so thought maybe sharing will help. In addition to Renn we had a boxer named Kai, officially he was my daughters dog and her emotional support as well, though we never used that title nor took him out to places and called him that, but he was. I must add he was our heart. He has had trouble in the past chewing his food and it was always thought maybe it was just his teeth but last week he began to salivate and choke while eating, not always but it just started to happen while at the same time it seemed his equilibrium was off, he would seem to walk stiffly like he was in pain and would lean toward one side and slightly flinch when petted. So off to the vet we went. The vet said it could be neurological and being a boxer more than likely was but since he has been fine we would tr y a course of antibiotics for a few days along with a pain med to see if it could be a inner ear infection, as it was his ear the flinched when you touched it. Well on day 2 we thought we saw a slight improvement but the following day Friday we were once again back to where we started. I called my daughter and told her and she came home from work. Our vet talked to a few of the specialists in the area and they all felt he should have a MRI, which could be done at a specialty hospital about an hour away. That was to be done Wednesday this week. I however opted to have a ultra sound done at our local ER vet, to see if it would show anything as we really wanted something done the sooner the better as our vet said. So that was to be today. However God had other plans. My daughter took him for a very short walk and into our backyard where he seemed to choke on saliva, so we came into the house where again he began again this time much worse, one would think he had a wash load of saliva and he was choking and he stood there as we tried to help and then he began to have a really bad seizure. He stopped seeing but the choking continued and my daughter got his 84 lbs self into my car and we rushed to the ERVet. It was really the most awful thing I've ever gone thru in all my years. WE along with the vet and assistant and my daughter got him out and inside the clinic. They gave him meds and a iv and a wet blanket as his temperature went to 107 +. His breathing was labored and hard and the vet said she felt he was going to seize again. We decided to let him go at his young age of 5 years and 6 months. Our vet along with two specialty vets felt the problems was all from a brain stem tumor. Right now our house feels so empty. Even with a bouncy poodle. He was the best boxer boy ever, very well behaved, no bad manners, would even come to get his mouth cleaned after eating. He was greatly loved and loved everyone he met. Rest in peace now my sweet boy.
