I have three...Sadie and Cincy lab mixes that live with me and Oreo, a 12 1/2 year old beagle/poodle mix that we got when I was 14, but still lives with my mom and dad. My parents also have two additional dogs they got since I moved out, Dazzi, a golden mix and Taggert an 11 week old Airedale mix they just got Saturday. We have not had all 5 dogs together yet (that is plans for tomorrow), but 4 has been interesting!
