I just now had to correct Alice for chewing on the wooden leg of my computer chair lol. At 11 weeks old they're teething, so they chew to ease that. Alice (who is done teething but still chewing all kinds of things
) seems to like to chew on things that are hard, so try KONGs or other toys that are hard like that. She also has 'stuffing free' plush toys that she loves to play with, but for actual chewing she prefers something hard (like my woodwork
). I just got a dog toy that looks just like a "key set" teething ring that you'd use for a baby and she likes that. At 7 months old I do correct her firmly with a "NO!" when she chews on something that's not one of her toys, but she's 7 months old, at 11 weeks you don't want to be as firm - just move them away from anything inapropriate and give the toy as a replacement. Basic rules for safety are obviously it can't be too small and you don't want anything that looks like it has a smaller peice that can be chewed off and swallowed (like the nose of a plush toy for example). For the harder ones, again, just make sure it's durable and pieces can't be chewed off. I like Nylabones (I get the "flavored" ones to make them more appealing) too, teenie tiny pieces start to wear off after a while, but they're so miniscule it's not a problem.
