What type of jasmine is this? And is it toxic?

I live in Houston, and this is a picture or the plant in question http://www.flickr.com/photos/7372796@N07... . Any chance anyone knows what type of jasmine it is? This jasmine vine is on a nearby fence, and I want to know what type it is because some varieties are fatal to dogs (and I’m slightly concerned about my own dog, who is all too willing to eat random things off the ground). This website http://www.petfriendlyhouse.com/informat... lists some types of jasmine as non-toxic to dogs, while this website http://www.dcn.davis.ca.us/vme/DrSue/poi... lists all jasmine as potentially deadly. Does anyone know which jasmine plants are actually toxic and which are non-toxic? And which parts the toxic varieties are poisonous? (Leaves? Stems? Flowers? Seeds or berries? All parts?) Thanks in advance.

I don't think this is a jasmine in the botanical sense. It looks like a vine in the Apocynaceae family (in which case it will have milky sap) rather than in the Oleaceae family (which is where true jasmine belongs). Many Apocynaceae are poisonous (best example is the shrub Oleander) but very often do have white, sweetly scented jasmine-like flowers. Sorry that I can't give a more specific answer ...
