You're not the only one!! Pepper feels no need to even pretend he's interested in Kong. I bought him one - a baby size, he just sniffed it, I thought maybe he was too young for it? I got another one for him when he was around 6 months old and tried putting the Kong paste, peanut butter, doggie buscuits, even freezing it with yougurt - he just doesn't like it. He actually doesn't peanut butter at all. He steers clear of any toy that is made of rubber or plastic - but LOOOVES balloons. Weirdo
