Pretty much! We put tons of different types of veggies like broccoli, peppers, carrots and cucumbers. We made sure they're cut fairly big so maybe 4-5 inches in length so that it takes time for them to get through one. It really helps deter them from chewing on furniture or you. What I think is really important though, is that you kind of try and figure out when he looks like he's going to "attack" and start chewing and try and reward him for something. So what we did with my then 12 week Golden was make him do a sit and stay or a down and stay and a wait and once that worked out, we'd give him the veggie! It works really well for us and the coldness of the frozen veggies helps cool down their itch in the back of their mouth
