i got a lead for my guinea pig Charlie about 2 weeks after i got him i put it on him and he was fine he liked it but last week i put it on him and he went crazy like i was hurting him but i never put it on tight and i took it off coz he was squealing like little pigs do and i was stroaking him and it was everytime i touched a certain part of his back he would squeal so i put him back and the next day he was fine what is wrong is it the lead or just leads all together coz i wanna take him out side in the summer?
what can i do?
