Chocolate poisoning is particularly common at this time of year, especially with the large amounts of Easter eggs that may be around your home. Chocolate contains a chemical called theobromine, which can be poisonous to dogs, as well as most other animals, including cats, rodents and rabbits.\nHow much is too much chocolate?\nThe seriousness of the poisoning will depend on the amount, type and quality of the chocolate eaten. Generally speaking, the darker the chocolate, the more theobromine it contains, and therefore the more poisonous it is. White chocolate contains very little theobromine and although it is unlikely to cause theobromine poisoning, it is still very fatty and can make your dog ill.\nWhat signs can it cause?\nAs well as possibly causing vomiting and diarrhoea, chocolate is a stimulant, so it can cause excitement, muscle twitching, tremors, fitting and can increase the heart rate and blood pressure.\nHot cross buns\nGrapes, raisins, currants and sultanas are all toxic to dogs and it is believed the dried forms of these fruits are more toxic than grapes. At this time of year, it is therefore important that hot cross buns are kept well away from your dogs.\nHow much is too much?\nIt is not known why these fruits are toxic to dogs, or how much can be poisonous. Some dogs have eaten large quantities of this fruit and had no effects, while others have become unwell after very small amounts.\nWhat signs can it cause?\nAs well as possibly causing stomach problems, these fruits can cause kidney failure, which can sometimes be delayed by up to three days. Kidney failure may sometimes present as a decrease in urination, or your dog may also appear dull and show signs of increased thirst.\nPrompt treatment is important. If your dog does eat any amount, contact your veterinarian immediately.\n\n \nSpring bulbs\nIncidents of poisoning from spring bulbs are most likely to occur from dogs eating the bulbs in autumn when they are planted, or in spring when they begin to flower.\nDaffodils\nEffects from poisoning can include vomiting, stomach upset and salivation, but can escalate to dogs appearing sleepy, wobbly on their legs, or collapsing. In more serious cases fits and changes to heart rate, body temperature and blood pressure may occur. Dogs can also become unwell if the flowers are eaten, or if water from a vase containing daffodils is drunk.\nTulips\nThe toxins found in this plant cause irritation to the mouth and gastrointestinal tract and usually only result in drooling, vomiting and diarrhoea. Serious cases are rare, but effects could include heart problems and breathing difficulties.\nSpring crocus\nThese flower in spring and are said to be of low toxicity and may only cause a mild stomach upset if eaten. These bulbs are not to be confused with autumn crocus, which flower in autumn and can cause severe stomach upset, kidney and liver problems and bone marrow depression.\nWhat to do if you suspect your dog has been poisoned\nIf you think that your dog may have eaten, touched or inhaled something that it shouldn't have, consult your local veterinary practice immediately.\nDo not try to make your dog sick. Trying to do this can cause other complications, which may harm your dog.\nIn an emergency you can help your veterinary practice make an informed decision as to whether your dog needs to be treated by them, and if so, what the best treatment would be.\nWhere possible you should provide your veterinary practice with information on:\n\nWhat poison you think your dog has been exposed to (i.e. chocolate, ibuprofen, etc.). Include any product names, or lists of ingredients if relevant\nHow much they may have been exposed to (i.e. 500mg, 500ml, one tablet etc., even approximations may help)\nWhen your dog was exposed to the poison (i.e. 5 minutes, 5 hours or 5 days ago)\nIf your dog has been unwell, and if so, what clinical effects have been seen\n\nIt is easier for a veterinarian to care for a poisoned dog if it is treated sooner rather than later. If you are in any doubt, do not wait for your dog to become unwell before calling for advice.\nIf you do need to take your dog to your veterinary practice, make sure that you take along any relevant packaging, or a sample of the poison, i.e. parts of plant or fungi. Always make sure that you yourself are protected and cannot be poisoned in turn.
