Ok but how much oil do they have ? <| sep |> Jeezus . That is all . <| sep |> C ' mon man , at least Google before you post , it ' s not like this is secret knowledge <| sep |> That was it ! Does ' methinks thou doth protest too much ' apply to overusing size references ? <| sep |> If it ' s hot and you just need to pop into a store you can always just leave your dog outside the store or car . Mine waits for me outside when I run quick errands . Longer and colder temp I don ' t think it ' s an issue if the dog is used to it and not stressed out by being in the car alone . You may be surprised if you go for it and just bring the dog . It ' s the better to ask for forgiveness approach . If the dog is well behaved , people sometimes just look the other way . Note is a great idea , in fact I will start doing that myself .
