Genitals Sexing Guinea Pig

Honestly, I can't tell confidently from that picture if male or female.

Here is a link that may be able to assist you: https://www.cavyspirit.com/sexing.htm?

I'm not sure, either. The Y shape looks like a female, but those bumps on either side look mighty much like testicles.


If it's a male, you should be able to feel the penis bone by putting your finger crosswise the body, right at the top of that nubbin, and rolling back and forth. If you're lucky and there's a penis there, it may extrude, but you should for sure be able to feel the bone.

URI dosage

It’s a girl!!

I now have 3 new girls. This one and 2 others from a shelter. They went to the vet today and the two shelter pigs are being treated for a mild case of uri. They were prescribed 0.1ml twice daily enrofloxacin 22.7mg/ml oral solution. These piggies are 9 weeks old. The third piggy is 13 weeks old. Is this dosage safe?

Actually, young pigs are not usually given enrofloxacin (Baytril) because it can stunt their growth. They usually start them off on Bactrim and then switch to Doxycycline if the Bactrim doesn't work. Baytril is usually the last resort for URi's in young pigs.

Should I not give it to them? I was going to give once a day rather than twice.

I'd call the vet and ask why Baytril was chosen and if there's a better alternative. If the pig needs an antibiotic, it's better to have a small live pig than a large dead one that died because of the infection.

I contacted the vet about the baytril and asked if we could use bactrim instead and he got upset with me that I was questioning his knowledge. He said he prescribed baytril because my one guinea pig has a pimple abscess and the baytril will work better to take care of that and the baytril will also help the other two piggies from developing a unresponsive inflammatory disease like my last pig had. He said he is being cautious as he feels the other two may have been exposed to bordetella at the shelter. He has them on 0.1ml twice a day for 7 days and it says 22.7 mg/ml oral solution on the bottle would that be a low strength enrofloxican?

The Baytril won't harm them, other than to possibly, but not definitely, stunt their growth. And since they're already past the baby pup stage, they should be ok with it.
