If you have a dog lick matΒ or have been researching some recipes for homemade dog treats, you may have seen that peanut butter crops up a lot.
This is a storecupboard staple for a lot of humans, so hearing that our four-legged friends can also share it is great news. However, don’t rush for the spoon just yet. Yes, dogs can have peanut butter, but not all peanut butter is suitable for them.
For dogs, peanut butter that has no xylitol is suitable. It also needs to be fed in moderation, so don’t give them their own jar to keep them busy.
Are dogs allowed peanut butter?
The only peanut butter which is safe for dogs to eat is any which does not contain xylitol. Xylitol is toxic to dogs. It is an artificial sweetener used in human foods instead of sugar. So, many ‘sugar-free’ sweets will contain xylitol, and it is also commonly found in chewing gum. So, if the label states that xylitol is an ingredient in your peanut butter, you need to keep it for human use only.What other foods contain xylitol?
As well as peanut butter, you also have to check the ingredients of any other human sweet treats before giving them to your dog. Foods that may contain xylitol and should not be given to dogs include:- Cookies
- Puddings
- Biscuits
- Non-fat Greek yoghurt
- Preserves (such as jam)
- Flavoured water
- Sugar-free syrups and honey
If in doubt, just avoid giving your dog any human sweet treats. It isn’t worth the riskMany chocolate products also contain xylitol, as chocolate is naturally bitter. Dogs shouldn’t be having chocolate anyway. The same applies to chewing gum, although this is the biggest source of xylitol poisoning in dogs in the UK. Xylitol is often also present in household items such as human toothpaste or nasal irrigation sprays, so it isn’t just food you need to keep out of the reach of dogs. In the UK, xylitol will often be listed as such on food labels. But if buying from the USA for example, you may also need to look out for terms such as Birch Sugar, E967, Meso-Xylitol, MΓ©so-Xylitol, Sucre de Bouleau, Xilitol, Xylit, Xylite, or Xylo-pentane-1,2,3,4,5-pentol.
Why is xylitol bad for dogs?
Xylitol is toxic to dogs. Even in small amounts, it can give a range of symptoms, from mild hypoglycemia to liver failure and potentially death if not treated. It stimulates the pancreas to release insulin. This surge of insulin causes hypoglycemia. Because there is so much insulin in the bloodstream, it causes a huge drop in blood sugar levels. This can result in:- weakness
- disorientation
- collapsing
- lethargy
- tremors
- seizures
