You have received very good advice so far.
IVDD seems to be what the problem is here, at least to me.
Right now crate rest is VERY important!
The poop on demand thing sounds weird, but it does work. You would be surprised how easy it is!
Although it is too early to think about a cart yet, I will post this information about carts.
We have 9 dachshunds in all.
We have 2 dachshunds that are paralyzed and use wheelchair carts. We also have Riley, a dachshund that we adopted as a downed dog but he recovered. Here is his story:
We also have Johanna, a dachshund that was left paralyzed from an attack with a baseball bat.
Here is a link to when Johanna and I were on the news in Boston last year.
Pork Chop has a slipped disc in his neck that has left him paralyzed.
Handicapped and disabled dogs can live very happy and healthy lives, as I hope you can see. Remember, being disabled doesn't mean being destroyed!
It is important to keep a good, positive atitude right now. I know it is very difficult, but it is so important right now. Your dog will feed off of your energy, and you want to give them the best possible chance to recover as quickly as possible.
If you have any questions, please feel free to ask. Good luck!
