I follow all the safety procedures requested of me. I never let dogs off-leash, even if the owner says it’s okay. I personally don’t want to be liable for a runaway dog that could lead to conflict or injury. I make sure they don’t have access to foods they may be allergic to or things they may chew on and ingest. I keep dogs separated if they get territorial during feeding times by whatever means the client suggests. While walking I generally avoid encounters with other dogs, just in case. I only allow for mingling when someone tells me so and so down the street is their buddy. I make sure gates and entrances are closed. I’ve never had anyone get loose and don’t intend to. I also make sure that I know where the pets are when we are home. I’m hyper-vigilant because their safety is important to me.
