Hi all, this query is primarily about bonding but also includes some health concerns, so please direct me if I have posted this in the wrong sub! Currently, my youngest girl seems to be exhibiting symptoms of depression and is acting like she has fallen out with the herd.

She has been to the vet and been given a clean bill of health with no obvious signs of illness. She is bright and moving fine, but has stopped eating unless I hand feed her (I have since been syringe feeding water and critical care, as well as coaxing her with fresh grass and vegetables which she is eating in moderation, but nowhere near as much as usual). She ignores the other girls, scuttling past them and only briefly joining them to eat high value food like greens at dinner time; she is not interested in hay, pellets or water, she just finds a hidey to stay in for most of the day.

I have isolated her for a couple of nights already to see if she felt better about coming out to eat and drink, but even away from the others, she has made no attempt to leave her hidey. She is young, only about 9 months and she has lived in the herd for about 3 months now. She is a rescue and I am wondering if she has had a fight with another sow that has led to her feeling scared and insecure. She has no injuries and neither do any of the others, but it seems she is psychologically changed and with her lack of appetite, I worry that her health is going to deteriorate if she doesn’t start to act normally again.

I do, however, have the option to bond her to a neutered male, so I’m wondering if she would be better taken from the herd to live in a pair with a male, or is it too soon to consider something like that? Do sows often recover their bonds with other females, or is it more likely that her self-isolating behaviour will continue unless she is removed?
 
How big is your group? How are the others acting?
Is your girl acting more herself when seperated from the others?
Have there been any changes in the environment or anything that could have spooked your girl?
Is your vet cavy savy?

It is a bit unusual for a healthy sow to stop eating over a longer period of time just because of a minor upset in the group after living with this group for three months.
But guinea pigs can be rather complicated.
 
They are a group of 8 and the others are all acting perfectly normal. They have ample space and multiple floors for the very reason that they may like to get away from each other now and then, as well as multiple feeding stations, so it’s not hard for an individual pig to avoid another that they might have fallen out with. She is no more herself away from them than she is with them and there have been no changes to their environment, diet, or any newcomers to upset her. The vet did a very thorough examination of her as my first thought was that she might be developing a URI when I noticed her acting withdrawn and puffed up; she has had her teeth checked, temperature taken etc but the vet couldn’t find anything physically wrong. She is interested in eating grass and veggies, but as described, she seems to just confine herself to a hidey and does not come out to eat hay or drink water, which is my main concern. It’s a tricky one, as it appears to be behavioural rather than a health problem 😣

Hi and welcome

Puffing up is a pain symptom; unfortunately, it is rather vague and usually indicates an internal pain source of some sort, including internal masses or even a brain tumour.

Would your vet trial a significant short term dose of painkiller to see whether symptoms she perks up or not? This would then give you another avenue to pursue. It won't work with a cosmetic dose of metacam.
