Hello. This is Dr. Christian. I'd like to help Yukon.
Is he able to keep any water down?
The main goal overnight is to keep him hydrated and his blood sugar up. There really aren't any medications that you can give for vomiting. Don't worry about any food overnight. How much does he weigh?
Try giving 2-3 tablespoons of water mixed with honey or karo syrup every hour. That will help keep his blood sugar up and perhaps he can keep that small amount of water down. If he can't even keep that down then you can smear the honey/karo syrup on his gums and that will absorb to keep his blood sugar up. It doesn't have to be much, a teaspoon would be enough.
Unfortunately, this is one of those situations where I would recommend a visit to the emergency vet but that isn't an option here. The best you can do is to keep him as hydrated as you can and prevent a low blood sugar. Making sure he keeps warm is also important. You can use a heating pad but always put it on low and put a blanket between him and the pad. Even a pad set on low can burn the skin if he is directly touching it.
Unfortunately, it's impossible to know under these circumstances. If your vet opens before 9 am then I'd be standing at their door the minute they open rather than waiting until 9.
If you think he continues to worsen despite the honey then you may have to make the trip tot he emergency vet.
I'll be online for another 1/2 hour or so.
Good luck. I hope he feels better soon.
You're very welcome. That a pretty good sign. :)
Hi Dr. Christian K.,
Just now have a chance to update you about Yukon... Thanks to your advice Yukon made it through the night... I set my alarm for every hour and rubbed honey on his gums and turned up the heat in the room where he slept to 84 and at 7 a.m. I packed him up and took him straight to the vets office (Tuesday October 9th) and he was admitted to the hospital... six days later he came home saved from PARVO... My regular vet told me that your advice helped me save him... keeping his glucose level up was the most important thing I could have done for him... PARVO cases are hard to save but my vet told me that you advice had helped keep his glucose level and his body temp up which helped keep his organs strong till the IVs could be administered with the proper meds and glucose going into him to help him overcome this awful virus... Thank You again for all your help and for saving Yukons' life...
You don't know how happy I am to hear that. I'm so glad he's doing well. You've made my weekend. :)
