Pet lovers welcome their dogs into the garden. Dog-loving gardeners train their pets to be well behaved additions to the home gardening experience. Still, curious pets, particularly young dogs and puppies, risk exposure to toxic plants. Protect older animals, whose sense of sight and smell has diminished, from plants that produce irritants or are poisonous. Trellis plants exist that are perfectly safe for pets and their owners.
According to the American Society for the Prevention of Cruelty to Animals (ASPCA), Jasminum species plants are not poisonous to dogs. Winter Jasmine is a vining shrub to 15-feet tall. Yellow, scentless flowers appear in very early spring on leafless stems followed by dark-green summer foliage. Summer Jasmine produces very fragrant white flowers throughout the growing season. These plants grow to 30-feet high for trellis cultivation. J. officinale "Aureum" has golden foliage. "Argenteo-variegatum" has white-edged leaves.
Roses are safe for dogs. Climbing rose choices in size and color are wide and varied. Jeanne laJoie is a climbing pink miniature rose growing to 10-feet long. Plant this small-flowered mini alongside the large-flowered pink blend Eden for a summer flowering display in pink and cream. Zepherine Droughin is nearly thornless, blooming heavily with deep pink roses in spring on a plant growing to 12-feet high. Peggy Martin is an easy-to-grow spring bloomer in light pink. Choose climbing roses for trellises according to color preference, growth habit and local growing conditions.
Star Jasmine is Trachelospermum jasminoides. This is not a true jasmine but is a valuable evergreen plant with intensely fragrant flowers beginning in spring and continuing into early summer. The vine grows to 30-feet long and is evergreen. It requires a support such as a trellis. Star Jasmine is also called Confederate Jasmine because it grows in the Southern U.S. in USDA hardiness zones 8 to 10, the area that once was the Confederate States of America. The ASPCA lists this plant as nontoxic to dogs.
Madagascar Jasmine's scientific name is Stephanotis floribunda. The deeply fragrant flowers are used extensively in bridal bouquets, giving the plant the common name of Bride's Flower. This tropical plant is grown on a trellis indoor or in the greenhouse where not adapted. It may be moved to a protected outdoor deck or patio to bloom during the frost-free months. This charming, fragrant plant climbs 10 to 20 feet. According to the ASPCA, Madagascar Jasmine is not poisonous to dogs.
