Thank you ladyjane.

Well I'm trying to be circumspect but I think when I looked at her ears this morning they seemed a wee bit less red. She also seems to tolerate the pentoxifylline well. (Please don't let me jinx that!)
However she's been gagging and trying to vomit for the last day or so on and off. I don't know for sure what is causing it yet, but today was the worst I've seen since she went into the hospital for those four days.
She also has itchy face. She has a few welts on her muzzle and when she is awake will try to rub her face on anything she can reach.
The vet wanted me to begin using sucralfate again but I wonder if we're placing the dosing of that too close to the other medicines or to her meal time? He said at least a half hour before I give the pentoxifylline I should give the sucralfate, but I also need to try to get her to eat right before the pentoxifylline, I think that may be too much altogether for her poor tummy.
I'm hoping she is not developing an allergy to the food already. She's only had three helpings, but she sure wanted to bring this mornings' back up.

She'd also had the sucralfate a half hour before I fed her though, so not sure if it wasn't that. I know it gave her stomachaches and cramping when we used it before. I wonder if it could be responsible for the reaction on her face as well?
She is resting comfortably currently. I can't get anything done she is sat in my lap all day! (Not complaining!)
Her poor leg though where they had the IV. The skin is raw at the elbow, I think the bandage irritated it...and the hole where they inserted the needle looks inflamed. Using neosporin on both as per vet's instructions. The last thing we need is to add another med at this point, don't want her to have to need antibiotics too.
Do you have any experience with sucralfate in your pups, ladyjane? If so has it ever caused stomach upset?
