Are the dogs malnutritioned or in bad health? If not i think that you should mind your own business. The only way that you should get involved is if they are in bad shape.
Depending on where they live, country or in town, that is way to many animals in a trailer. If they have their windows open when they are smoking they may be ok. But ya you do have a dilemma if you are that concerned about the animals welfare maybe you should get animal control involved.
I understand. But there is nothing to do unless you have the courage to address them directly. Telling them it is their right to smoke but in your opinion, it is harming the dogs and it is your hope the dogs can be healthy. Ask them if they have given any thought to placing them in an environment free from the smoke. And then listen to what they say. There is only a small chance you can help, but it might be worth a try.. Thank you for caring about those little dogs.
