In order to encourage Molly not to chew on the sofa, computer wiring, kitchen chairs, coffe table legs, carpet, etc. I got some bitter apple spray. She avoids it for maybe 30 seconds while it dries and then it doesn't seem to faze her one bit. I was wondering if you use bitter spray, what type do you use? I was thinking the rosemary stuff might work better, but before I start buying every spray at Petsmart I was hoping for some advice.
