It could be, Trish. Morning glory (Ipomoea spp.) is a member of the Convolvulaceae family, and this plant (especially the seeds) contains hallucinogenic alkaloids similar to lysergic acid, or LSD. If enough of this plant material is ingested, significant and potentially even life-threatening central nervous system effects are possible. Because of this, it is a good idea to keep this plant material out of your pug’s reach.
