Do toy poodles bark a lot?
Toy breeds, all toy breeds, tend to be a bit high strung. They
are typically a bit sensitive to changes in environment and
anything new introduced to that environment, even as simple as new
sounds. The one way any dog will react if stimulated, say by new
environmental factors, is to bark. This is how they communicate
(one way, the primary way) and they will do so to alert their alpha
(typically you) to potential danger or strangeness.
Toys are also easily excitable. This seems to be one of the
reasons that those who own toys choose them. We, like dogs, relate
to those around us, and we thrive on attention from them. Dog
owners fill some of that need for connection by the relationship
they have with their dogs.
In short, the animal will take its cues from the owner and the
training they have received, but they will also be driven by their
own personality and demeanor. Most toys tend toward hyperactivity,
so yes, they do tend to be a bit more vocal and "bark a lot."
