Darius Kevin Wessell Lawn Mowing Service Dog got sick from licking fertillizer Huntsville, Alabama

When I was hiring him I told him that I had dogs and I didn't want him to put:

1. Fertilizer
2. Weed killer
3. Any other chemical substance on my lawn. 

These harsh chemicals can hurt dogs and I didn't want my dogs to get sick. My dogs are very important to me and I didn't want anything to happen to them. I'm gone for work all day so my dogs need to be kept outside. They have a doghouse and a kennel so they can go in if they need shelter. I hired Darius Kevin Wessell Lawn Mowing service and I specifically instructed them about my dogs. I breed dogs and these dogs are my babies. I love them like someone would love their children. I mean, I really have a close relationship with my puppies. So when I came home and saw a bunch of little yellow flags all over the place I went into my backyard and took the dogs in my arms and have to give them baths. I took them to the vet, which cost me money, and he told me that they are probably fine. But I know my dogs so well and they were not acting fine. I think they were sick because they licked the grass that had the chemicals on it while I was at work. So, my advice and helpful tip would be that if you hire this guy or any other lawn care companies that incorporated into your agreement that you specifically state in writing that nobody should put chemical substances on your grass. I just can't stop thinking about this because I would never do anything to harm my dogs. This is the first time they have been exposed to anything that might be harmful to them.
