Some guinea pigs aren’t interested in being the dominant pig, so they form friendships straight away. After Chanel and Grace had been sniffing and communicating with each other through the divider for two weeks, we felt it was time to introduce them. We found that Chanel and Grace wanted to determine their leadership positions as they both wanted to be the boss. For the first few days, Grace was bullying Chanel by humping and chasing her around the enclosure but thankfully no harm or distress occurred. Eventually, Grace understood that Chanel wasn’t interested in becoming the dominant guinea pig anymore and their bond started to form.
