For the most part, localized muscle aches and pains can be treated using home care strategies to reduce the inflammation and promote healing. In the early stages of muscle aches caused by injury remember to use PRICE: Protect, Rest, Ice, Compress, and Elevate.
Dog fouling applies to faeces, not urine. If dogs were repeatedly urinating on your garden causing a foul smell and you asked the person/s to stop allowing their dogs to do this, yet they persisted, it 'might' be classed as some sort of nuisance.
Urine also contains salts that can be harmful to some plants. Most grasses can handle a certain amount of dog urine without adverse effect. (Smaller dogs more so than larger dogs) Tiny dogs may leave behind no damage at all. The exception may be during the heat of summer when lawn dog damage is most prevalent.
