My husband and I drove a couple hours out of our way to adopt a new cat from a shelter...While there we browsed the dog area and I was heartbroken when I found a 12 yr. old miniature dachshund seemingly terrified by the whole ordeal. She was brought in by her former owners because she was having bladder control issues and the shelter was told that her diet had always consisted of table scraps.

Needless to say her teeth were in horrible condition.
We left knowing that it would be impossible to transport her, a new cat and a toddler on a nearly 3 hour drive. Most importantly, my husband and I are in the middle of a move and we're unable to give her the proper care at this immediate time. Nonetheless, I couldn't keep her off my mind so I immediately started contacting rescues...after several phone calls and lots of pleading she was picked up yesterday but I have committed to fostering her and need to pick her up within 2 weeks.
So...that's her story. I'm super relieved to have gotten her out of the shelter (Her chances of being adopted were slim to none considering her age and reason for surrender) but now we have three cats and three dogs...WAY more than I ever intended. She's also much older than I have much experience with, is there anything I should be prepared for or with?
(I should add that I have plenty of Doxie experience, she won't be using any stairs and her mobility seems fine for now but I know what to keep an eye on)
