I have three guinea pigs, two that are around a month or so old, and one that is one year old. The one-year-old one is named Oreo, she is an American guinea pig. Ever since I got her, 5 months ago, she had been losing hair (more than the other guinea pigs) but recently she has been losing a lot of hair. It has gotten to the point where just picking her up gets me cover in hair, and brushing my hand across her back pulls out hair. She doesn't have any scabs or bald spots that I can see, but her coat doest look perfect either, its kind of rough? Most American guinea pigs that I've seen have a smooth coat but hers is always kind of disheveled looking. I'm a new guinea pig owner so I don't have much experience with guinea pigs. All I kind find about hair loss is vitamin C deficiency, parasites, and mites. But she isn't scratching much and doesn't have any scabs. I am giving her more vitamin c but in the meantime, I am trying to see if there are any other possibilities. I can bring her to the vet but I just can't afford to bring her to the vet and have it just be a normal thing most guinea pigs do. So if anyone has any experience with this, or thinks that they know what's happening I would really appreciate some advice. Thanks!
