Protection from Weather
Dogs with outdoor kennel areas need protection from adverse weather. Even when you put a doghouse in the kennel area, attention to plant placement can increase your dog’s comfort. Shade from trees and shrubs cools dogs in hot weather. Deciduous plants keep dogs warmer in winter by allowing sunlight to reach their kennel after plants drop their leaves in autumn. The U.S. Department of Energy advocates plant placement as a windbreak, and planting low-growing dense evergreen shrubs outside the north and northwest areas of your dog’s kennel buffers cold winter winds.
Many landscape plants are toxic, although that does not mean they are necessarily fatal. Common plant-poisoning symptoms for dogs include stomach discomfort and burning of the mouth. However, some plants can be deadly to dogs that eat them, and these plants can grow quickly into fenced kennel areas if you plant them too close to the kennel. All parts of azaleas and rhododendrons are poisonous and can cause dogs to lapse into comas. Cycads contain a toxin in the roots and stems that damages liver function, which can cause a dog to bleed to death, according to Dr. Murl Bailey at the Texas A&M College of Veterinary Medicine. Bailey also advises against planting oleander, another poisonous plant that can kill dogs.
Dogs instinctively guard perimeters around their territory. If your dog has access outside the kennel into your fenced yard, leave an unplanted path around the inside perimeter of the fence. This lets the dog patrol its area without damaging any plants in this path. Consider mulching this area with wood chips or pinestraw to cover sparse turf areas that your dog creates. Left unmulched, bare spots in your yard create mud puddles each time it rains.
Insect pests not only annoy dogs, but they can also lead to skin infections from excessive scratching or carry parasites such as heartworms and tapeworms. Although mint does not kill insects, “Mother Earth News” reports that ants, flies and fleas avoid plantings of mint. Fennel also repels fleas, as evidenced by the gardeners' rhyme “Planting fennel at your dog’s kennel.” You need to plant fennel seeds where you want the plants to grow, because this herb resists transplanting.
