Yes, but mildly. Holly leaves and berries are toxic to dogs and cats, but they usually cause no more than an upset stomach, and the spiky leaves put most pets off.
Holly (Ilex) contains saponins, which irritate the stomach and gut. The ASPCA rates the leaves and berries as low toxicity. The spiny leaves can also scratch the mouth, which is often what causes the drooling and head shaking. Wreaths and garlands often combine holly with mistletoe, so check what else was in the arrangement.
Vomiting, diarrhoea and lethargy, usually within a few hours. Drooling, lip smacking and head shaking can come from the spiky leaves scratching the mouth.
Remove any leaves or berries from your pet's mouth and check for cuts. Offer fresh water and keep an eye on your pet for the rest of the day. Call your vet if vomiting or diarrhoea lasts more than a day, if your pet ate a lot of berries, or if it seems unwell.
