Do you feed your pets "human food" or table scraps? Not all human food is safe for pets and adding extra scraps to their diet can contribute to obesity. There are some things in particular that cause problems. Cooked bones can shatter and get caught in the throat, stomach or intestines. Due to the fat content they can also cause pancreatitis and in large amounts there is a risk of severe constipation as dogs that are not solely eating raw foods do not have the correct acid pH in their stomach to digest the bone.
Some vegetables can also be toxic. In particular onions, garlic, rhubard and raw potatoes are all toxic to pets at varying doses. Fruits such as grapes (especially when dried as sultanas or raisins) and avocado are also toxic. Stones from peaches, nectarines and apricots are just the right size to get stuck in the intestines, (so is corn on the cob) but they also contain toxic chemicals in the kernels.
Leftover fat and trimmings from roast meat or bacon can also be very dangerous to your pets as it can cause pancreatitis. Pancreatitis is a potentially fatal disease and causes extreme pain to your pet!
So keep these things in mind if you are going to give human food to your pets.
