I’m going out on a limb here, but the compound leaves with the significantly larger one at the tip plus the overall appearance of plant and flowers tell me that you have a pink jasmine (look at the buds) or Jasminum polyanthum.
I would have expected the flowers to be wider open, the tips of the petals forming a plane or even slightly bending backwards, but it may be that they are not yet fully in bloom. They should have a very distinctive sweet jasmine scent (hence my comment above).
Sources vary whether the plant is poisonous, but even those that claim its theoretically not, recommended keeping pets away from them and in case of ingestion, to monitor them closely.

When a pet shows any signs of discomfort or sickness after ingesting anything suspicious, call your vet!
