Our pup is 5 months old and we have been using a harness with a strap that plugs into the seatbelt buckle. However, she is becoming quite large (breed unknown but starting to look pointer ish) and I don't think this will be a possibility long term, especially when the children are also in the car. W iththe recent weather, there is also mud everywhere in the car!
When we go out, we have noticed that most dogs seem to jump into the boot so are wondering if we should do this? I think having a crate in the car permaantly could be a pain. I am just intersted to see what other pepole do with medim to large dogs, and also how to reduce the mud (wishful thinking!)
