It's loving the experience you and your dog will have with me! I had a westie and a pitbull no matter what kind of dog you have I'm okay with it there's no problem. I'm not scared of the jumping or anything like that so if you have big or small and he/she jumps please please don't worry about it! That happens and it will happen. During our walk if your dog looks thirsty I'll have water with me and I'll definitely give them water no worries about an unhealthy pup while they're with me! Same care and treatment will be done as if you were walking them yourselves. If you need longer than 30 minutes just let me know and I'll work it out
