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.
The concentration of urea in dog urine is basically too much of a good thing for grass and other plants. Other salt and compounds such as potassium may also contribute, but nitrates are known to be the No. 1 killer. The main thing that makes urine more damaging is volume. Large dogs deposit more urine. Females tend to deposit it all in one location. Male dogs are easier on the grass but hard on trees, where urine sprayed on the trunk can filter down to the roots and in large enough volumes can kill the entire plant. Just how much dogs contribute to the poor health of some city trees is under debate.
