It sounds like you might be expressing frustration about barking, whether in a literal sense (with dogs) or perhaps metaphorically (about not voicing your thoughts). If you're referring to a dog that barks excessively, training techniques, positive reinforcement, and redirecting their energy can help.
If you're talking about personal expression and feeling like you need to hold back your thoughts or feelings, it can be beneficial to find constructive ways to communicate. Bottling up emotions can lead to stress, so finding a healthy outlet is important.
Could you clarify a bit more about what you mean?
