Not sure I get your question....are you worried that the snake might confuse your dog for a mouse due to color??? They go at things based on smell...the dog unless rolling in mice terds...smells totally different. Not too mention unless it is a tiny tiny dog and a huge huge BP...never gonna happen! I though keep the dog away from the pyton. One bite can really do serious damage to the snake!!
