    Old wound? - Can anyone help me identify this lump please?

    Hi forummers! This is my first post here although I have frequently benefitted from the shared knowledge on this site! Today I adopted a 2.5 year old rex called Luna from a family where the children had lost interest in their GPs and so they were becoming an burden for a hardworking mum. Luna...

    Inflamed lymph node

    Hello I normally do a body check at least once a week on my piggies to check for lumps etc. Unfortunately today I did find a small lump on my 5 year old piggies neck. It is around the size of a pea and is free moving. I called the vet and got an appointment same day. She was diagnosed with...

    Lump under guinea pig’s nipple.

    I’d been noticing a strange brown liquid coming from Peppa. At this point I hadn’t been sure where it was coming from as there wasn’t anything there that I could tell from. It had only happened twice until tonight it happened again and I decided to look at the source. It was coming from her...

    Weird lump in pelvic area

    So when I picked up my guinea pig, Sabrina, I noticed that she had a weird lump (sort of between her nipples) when I pushed on it, it moved. It was about the size of a penny and very firm. My first instinct was to squeeze it a little to see if it hurt (it didn’t) or was something that would just...

    Lump Under The Chin

    Hi! Our piggy has a lump the size of a grap. It's located under the jaw, if you imagine sticking your finger through a mans adams apple, that's where the lump is. The vet took xrays of his jaw, because it's very large and not normal, but it was not causing him any pain. The vet did not mention...

    Multiple Guinea Pig Lumps

    Hi all, Around 2-3 months ago I found two fairly large lumps around the back legs of my piggie. Took her to the vets and turns out they were benign. But within the last 2 weeks, i’ve discovered more smaller, movable lumps all around her. Mainly on her stomach, and one on her side. She’s 5...

    Guinea Pig Lump/growth

    My Guinea Pig has a growth/lump on the centre of his back. It has a scab in the centre and in my opinion looks like it is filled with something, as if I squeezed it (which I don't plan on doing) something would come out. This is especially due to the scab in the middle seeming like it goes deep...

    Abdominal Lump

    My female guinea pig has a firm, grape sized lump on her lower abdomen. It is near a teat, at a spot where she would occasionally bite herself, leaving wounds or bruising which would heal quite quickly. She is almost 7 years old and does not seem to be in any pain. Anyone seen this on their pigs?

    Young Sow Cysts

    A couple weeks ago I noticed Bubbles had two lumps on each side of her belly, near her legs. I felt Nymeria and kind of felt something too so I assumed it was just normal and it was her organs. Just a few days ago I found out you can feel ovarian cysts in guinea pigs. Could it be cysts? I don't...

    We're Having The Worst Lucky With Guinea Pigs At The Moment.

    Hi guys, It seems We're having the worst lucky with health at the moment. I'll admit I've been feeling quite poorly these past two weeks so I haven't been as hands on with the piggies as normal, if I feel this bad I don't want to give it to the piggies! But alas, last night while I was...
