1. Watch Out for Poisonous Flowers
Tulip, hyacinth and daffodil bulbs can damage a dog's mouth and esophagus, causing drooling, vomiting, severe diarrhea or even abnormal heart rhythms, depending on the amount consumed. So be sure to keep bulbs out of reach before planting says Justine Lee, an emergency critical care veterinary specialist and Associate Director of Veterinary Services at the Minneapolis-based Pet Poison Helpline.
When planting, place the bulbs in deeply, surround them with plenty of mulch and then supervise your dog when it's outside to make sure it's not digging them up, Lee advises. Once the flowers are out and have bloomed, they generally don't pose a threat, as it's the bulb that's the most poisonous.
Also be very careful with lilies. Just a couple of leaves from certain lilies, like the day, Asiatic and Japanese varieties, can cause severe kidney failure in cats, according to Lee who said she dug up all the lilies in her yard in case her cat ever gets outside. "My own sister's cat died from it," Lee tells Paw Nation "Cats will always chew on plants. They're just curious and want to try something different. But one or two leaves will kill them."
2. Be Careful With Common Fertilizers
How you treat your yard is very important, as even organic supplements can be toxic to your pet.
Blood and bone meal are popular organic fertilizers, and dogs love the taste of these meat-based products. But ingesting blood meal can cause vomiting, diarrhea and severe pancreatic inflammation, while bone meal can create a cement-like ball in the dog's stomach, potentially forming an obstruction in the gastrointestinal tract and requiring surgery to remove.
