Please tell me you are not feeding your dogs human meat!!!! You mean steak intended for humans, yes?Plus, he devoured some human rump steak (apparently a good cut of steak, I hate even the smell of it though).
All kidding aside, I am so happy to hear that the test results are coming back with good news. Once they have eliminated all the scary scenarios, what is left to consider? Is there any connection between the mass in the rectum and the leg weakness? Could it be putting pressure on something?
