My two male guinea pigs have been scrapping a bit recently. Nothing serious but I am concerned as today I notice that Puddles has a bit of fur missing and there is a little scab. I bought Puddles on 1 August and Smudge a few weeks later. They were both 6-8 weeks old when I bought them. I let them run around every evening and tonight they had another scuffle whilst they were out. There was a lot of teeth chattering going on and Smudge was chasing Ruffles. They also seem to scent a lot and it stinks. Is it because they are young and trying to work out who is dominant? Most of the time they seem okay together and when I put them back in the cage they just lay on their house together but both were breathing heavily.
Would getting them neutered help or is this a bad idea? Please help as I'm sure they like each other really.
