Drought-tolerant plants that are non-toxic to dogs

QUESTION: I am looking for drought-tolerant native plants non-poisonious to dogs. We are putting gardens in an area the dog has access to, and she likes to sample the darndest things. South side of the house, close to the slab. Light 6+ hours/day. Nothing too tall - 2'-3' max for the base. Will be in a gravel topped (rock) garden. Some succulents would be nice. A few possibilities I gleaned from your website are listed, but I don't know if they are poisonious to the dog: Blackfoot daisy; Texas creeping-oxeye; Texas sacahuista; Red yucca; Texas yucca; Prairie verbena; Heartleaf rosemallow (hibiscus); Mealy blue sage; and any salvia. Thank you for your suggestions.
On the ASPCA list I found these plants: 1) Yucca spp. are on the list indicating that all species of Yucca should be avoided around dogs. 2) Hibiscus syriacus (a non-native) is on the list, but not the native one you chose, H. martianus. None of the other databases listed any members of these genera as being toxic so you will have to use your own judgement as to whether or not to plant the yucca or the hibiscus. Only one database, Toxic Plants of Texas, had a species of Salvia listed and that was Salvia reflexa (lanceleaf sage), a sage that grows in western Texas. Of course, just because a plant doesn't appear on any of the databases isn't a guarantee that it might not be slightly toxic to your puppy, but it does make it more likely that the puppy won't become ill from eating or chewing on a small amount of the plant.
You can check the Texas—Central Recommended list for other possibilities and check them against the toxic plant databases listed above. It's best to use the botanical name for checking the toxicity since the botanical name is more consistently reliable than the common name.
