At last. She seems happy enough but tired and hungry.
The vet had a long chat with me and showed me the x-rays that they took as food was going down. Everything looks fine and all seems to be working okay.
They have sent her home with 4 tins of food. I need to put about two dessert spoons of food in her bowl and mix it up with some water so it is pretty liquid. She can then have this three times a day - each time to be fed the same amount in 15 minute intervals - so a total of 9 little meals a day. It smells and looks revolting but if she is keeping it down then thats all that matters.
I am back again on Thursday to have her dressings changed and they will probably tell me then to put less liquid with it and see how she goes. Hopefully she will then go back onto solids.
If she still can't keep solids down the next option is to shove a camera down her throat and if that shows nothing then a moving x-ray which sort of films the food moving down into the stomach.
But the vets are very hopeful it is just a very bad reaction to the metacam medicine. She says that it does upset lots of dogs stomachs and if Millie had a dodgy tummy anyway (she did - food tends to go straight through her) then it could have had quite a bad effect on her.
I was worried that if she had to stay on a liquid diet for ever it was going to cost a fortune but in fact it is just a high nutrient dog food mixed with water.
Fortunately tomorrow is my last day at work so the feeding 3 x 3 times a day isn't going to be a massive issue. I can just nip home in my lunch break tomorrow - I only work a 5 minute drive away.
