Yes, Coton de Tulears do tend to bark a lot as alert barkers but are not “yappy” dogs or excessively vocal. Like all pups, they will bark to communicate. They may bark to alert their pet parents to the presence of strangers, during play, when they need something, or when they are excited or anxious.
Compared to similar small breeds, such as the Bichon Frise or Maltese, Cotons have a moderate barking level, but less so than more vocal breeds like the Miniature Schnauzer or Chihuahua.
To decrease excessive barking, use positive reinforcement techniques, ensure your pup feels safe, and provide consistent enrichment with exercise, play, and interactive toys. Some pups become hyperactive and overly vocal when they are overtired or overstimulated. If your Coton de Tulear is barking more than usual, it can also be helpful to assess if they’re getting enough restorative sleep.
