I was nervous to do our new rescue girl Winnys nails tonight .... they needed doing so the other held her to his chest facing outwards and I quickly took the ends off... she started to squeal which made it worse it does take some practice x
The rescue where I had my girls from gave me a really good tip for knowing when they needed their manicure. She said put your one finger under the foot and if the nails are digging into your finger the nails need trimming if the nails are just touching your finger they are ok.
You can use clippers or pet scissors, or chicken out and ask whether a piggy savvy vet nurse at your local clinic would do them for you and show you what to look for in black nails. Many clinics will offer this service against a small fee when you enquire. Guide to Cutting Guinea Pig Nails
