1. Yes the times vary. The first day or 2 they are usually a litle groggy still, from the anesthesia, and may be a little sore. Most dogs are back to their normal selves in a couple days. Some dogs are back to their normal selves that night. But you still have to keep them semi calm & quiet until the sutures are removed, about 7 days.

2. No, they will have normal control of their bowels & urine.

3. You probably want to be home with them for the first evening & night, and you can usually leave them they day after. If they are very hyper & you don't crate them, then you may want to either stay home with them or confine them somehow, in a crate or small room.

4. You want to withhold or limit their food & water for the first half a day they are home. If they have sensative stomachs I'd withhold food that night & limit water. If they seem to be doing good & don't have a sensative stomach I'd offer them about a 1/4-1/2 of their normal food. And limit water. The next day you can feed them as normal, unless they still seem groggy, then feed about 1/2-3/4 their normal food. Do not withhold water unless they are really drinking a lot.

5. I doubt it. Some people ask their vets for it & the vets give it just for their (owners) peace of mind, but about 99% of cases I have seen it is not needed. Especially seeing as you have terriers, they should be back to normal in no time. I'd see how they are the first night, if they seem very sore I'd call the vet for a script, only one days worth thuogh, thats about all you'll need if any.

6. If they are fairly young (under 2-3 years or so) and are healthy & have never had any problems it's up to you, if you want it done for peace of mind, do it. But otherwise they should be ok without it. If however they are older, have had problems in the past etc... I'd get it done.

I'm sure they will do just great. Good luck & once again kudos to your spaying/neutering!
