Below is a list of some popular plants and foods that can be poisonous to dogs and cats. Now may be a good time for a reminder also about chocolate - it can be lethal to dogs in very small doses - and yes, some of you may have been giving your pets chocolate for years without a problem, but is it worth the risk? Make sure they cannot get to boxes of chocolates left around or wrapped up and left under the tree, or the chocolate treats that hang on the tree. Another big problem at this time of year can be turkey skin - it can cause serious gastrinal problems. Don't forget vets will be closed at Christmas and any call outs will be very expensive.
Might be an idea to check your vets opening hours, just in case and ask what their on call arrangements are. Also check you have enough supplies for any pets that are on regular medication.
Hope you and your pets have a safe and happy Christmas.
