I really wasn't looking for commentary on my decisions or situation. I find the conduct on this forum to be totally inappropriate. I came here looking for legal advice. I fail to see how your personal feelings are relevant. Honestly I probably won't be coming back to this site since it seems overrun with people who just want to spew negativity rather than simply give legal advice. But because I have nothing better to do, I'll try to wrap this up with an explanation of how I found myself in this situation.
Where I was living to begin with also had a dog, but that was not my property in the least. I urged them not to get one, but they did anyways. At least in that instance, I fully understood that I was renting and they could do practically whatever they wanted on the property. So in other words, I was between a rock and a hard place. A common theme in my life. I figured that partial ownership would give me more control since any more than nothing would be more. Also of course I'm not surprised that there is a dog. I was just hoping that between legal control and trying to convince my dad to get rid of it, one of the two would work.
