Hi!

Having your piggy vet checked (as you should with all new piggies unless you adopt from a good rescue with mandatory quarantine and vet care that only rehomes healthy guinea pigs) and put her on a good normal hay based diet (at least 80% of the daily food intake). She is young enough to catch up on her own. Good long term health is more important than filling her up with junk calories.
You can add a handful of alfalfa hay daily for the first month if you want to feed something richer; it is only recommended for pregnant and nursing sows and very young babies in that quantity as it is too rich for a daily diet.
Please ask your friends what her diet has been and whether she has had veg before. If not, only introduce one new veg with her meals in small quantities at a time to not cause diarrhea or bloating.

What to check and look out for in new guinea pigs (vet checks, sexing, parasites&illness)

Long Term Balanced General And Special Needs Guinea Pig Diets
Looks at all food groups, includes a balanced sample diet for starting out from and instructions as to what you can feed how often in which quantities. As our long term forum members (including me) that practise a similar diet with personal tweaks have noticed an increase in longevity and much less problems with urinary tract problems, it is not the worst place to start out from, I'd think. ;)

You may also want to consider getting her a same sex friend or a neutered boar for company, ideally from one of our
recommended good standard rescues if you can get to one. Guinea pigs live in groups and are not wired to live on their own. Having a friend will hopefully perk her up and make it easier for her to learn to eat foods she may not have had - there is nothing like the 'I want what you have' reflex! Young guinea pigs learn from their elders what is safe to eat and what not. The rescues we recommend have a mandatory quarantine/vet care and pregnancy watch and most of them offer dating at the rescue under expert supervision for a companion, so you come home with a new friend only if acceptance has happened and the piggies get on. The rescues also provide life long back up if the bond runs into trouble or you cannot keep your guinea pigs anymore. That is a lot of service and assurance for a little extra effort!
Companionship

Please take the time to look at our new owners guide collection of which all the previous links are part of. We are specifically addressing all the areas new owners have the most questions and worries about, from settling in and making friends with piggy whispering tips to understanding behaviour, housing and enrichment, diet and care advice as well as learning what is normal and not and how to spot illness early or how soon to see vet. We have also included links to recommended good standard rescues and vets in several countries.

Alfalfa based pellets until she is 6 months. Hay unlimited. Veggies. Introduce slowly in case she has never had them. How is she eating, peeing, and pooping? Maybe she is lonely too? I would check with a vet just to be sure. Can you get a look at her teeth? Teeth can cause a lot of trouble. The back teeth need to be checked too.
 
I’d definitely pop her to the vets to get her checked over, especially her teeth!
I’ve also heard dry, plain porridge oats are good for putting weight on piggies if they’ll eat them.
Good luck with your new piggy! :)
 
I can only reiterate Wiebkes advice. Introducing a good daily diet with a slow introduction of veg if she hasn't had it before is best. Please do not feed additional foods to "bulk" her up as she should gain weight steadily on the right diet and doesn't need an unhealthy boost to her weight unless it is recommended by a vet
 
Thank you all so much. She's doing much better now and is running around with her friends ❤
 
Sorry to hear about your new piggy.
I was in a same situation where I was appointed Lara's pet parent by a friend who didn't want Lara. I didn't want to see Lara without a home. This friend told me she didn't even know guinea pigs eat veggies. All Lara got was small amount of hay and little pellets. Needless to say, Lara was uncared for.

Now, Lara along with my boy Finn get three meals of veggies a day, occasionally some fruits, endless hay and some pellets. She is healthy weight and size. She happily roams around her room daily and talks loud to Finn who lives in another cage. :lol:. She talks and Finn listens.
 
Here is Lara, and as you can see, she hasn't exactly been skipping meals. :lol: She is eating her lunch, corn.
And no, she is not pregnant as she has her own cage and lives separate from Finn.

What friends have you got for her? If you weigh her each week there should be a steady increase in weight. Mine put on between 30-50g per week and that has been the case for the last 10 months, think he’s still growing now little chunky :dri:
