URI/Upper Respiratory Infection Texel Getting over Pneumonia - Need Advice Please!!

I would continue with the probiotics for a few days. They won't hurt him, and should help.

The lethargy may just be the result of having had pneumonia, or the lack of eating greens may be contributing to it. Weigh him daily, at the same time of day (before breakfast is best if you can manage that), and keep a record to see what his weight is doing.

Chewing is often a sign of pain, but not so much when they're just wandering around sampling everything.

Does he have any trouble actually eating things when he tries, or does he seem like he's having trouble chewing then?

I agree, continue with the probiotics.

There is a possibility that he wasn't eating as much as usual, and his teeth have overgrown. Ditto bpatters--does he have trouble chewing?

Also, are you sure he's over the pneumonia? Sometimes it can take quite a while to recover.

Thank you so much for the replies! We will pick up more probiotics from our vet today and continue to give him those. He isn't lethargy at all. He's actually running around, but sampling everything in site.

We had his teeth checked at the vet and I've also looked at them and they're fine. He was eating normally actually when he had pneumonia and the URI, which was odd. He isn't having any trouble chewing. He's eating twice as much hay and drinking a ton of water, which he didn't do prior to the illness.

So, we were leaning on that his digestive system is out of whack more so then his teeth since he's been able to chew fine. It's just his appetite for "greens" has declined and he's eating hay like there's no tomorrow and going through a big bottle of water daily. What would make a guinea pig want to eat more hay and drink more water? Do you think he knows that his digestive tract is not capable of digesting the greens properly so he his trying to digest them by eating more hay and drinking more water? I know he's not dumb by no means. You should see the things this guinea pig can do. He's the most intelligent guinea pig I've ever had in my 40 years of having guinea pigs. Thanks a bunch for all of your help!

How is he doing?

He's doing really well. We've been giving him more pro-biotics and he seems to be eating more greens now then before so, his digestive tract must have been messed up from the 14 days of antibiotics.

The only problem we have now is that he is wanting to chew anything and everything, including our new carpeting. Not sure why. He's always been really good with that and only chew on his toys until after we finished giving him his antibiotics about a week and a half ago. It's got us stumped!

But, we're very happy that he's gotten thru it. He's a very determined guinea pig that's for sure!
