Wheezing Crackling noise, no other symptoms?

[Guinea Pig Papa]

Both of these videos do sound to me like a respiratory infection. If Yoshi is still making these sounds, he could have a very stubborn infection. The best advice I can give you is to head back to the vet for another check. Respiratory infections in pigs can sometimes take weeks, and different antibiotics to get rid of.

Ok your Guinea pig is perfectly fine. That crackling sound is just her grinding her teeth together. My piggies do it to. It's how they show some emotion. Mine do it when they want food or enjoy the attention.

She's chewing. If she makes a crackling noise when she's not eating, post that and we'll see what it sounds like.
