is christmas tree water bad for dogs

The water used to keep a Christmas tree hydrated should be changed regularly to prevent it from becoming stagnant. If it does become stagnant, it may contain harmful bacteria that could cause illness if ingested by a dog. It is generally safe to have a Christmas tree around dogs, but it is important to keep an eye on them and make sure they don't chew on the branches or ornaments, and to keep them away from any stagnant water.
