are xmas trees poisonous for dogs

Yes, xmas trees can be poisonous for dogs. The needles from the tree can cause gastrointestinal irritation if ingested and the sap can cause skin irritation. Additionally, the lights and decorations on the tree can be a choking hazard if they come loose and are accidentally swallowed. If you have a dog, it's best to keep the tree out of reach and supervise them closely while it's up.
