This week on our homemade diet page there is the grim spectacle of people telling other people off. One feeds their dog walnuts, and the other tells them they shouldn’t.
This debate is but a taste of what appears online. But who is correct?
Like with all internet myths, there’s a grain of truth in there. Let’s find it!
Are Walnuts Safe For Dogs?
Walnuts are safe to feed to dogs, as long as you keep five things in mind:
- Walnuts in shell can be dangerous especially for small dogs. In a dog’s rush to eat them, they may swallow the shell leading to intestinal obstructions.
- Walnuts fallen from the tree are extremely dangerous due to a black mould that causes tremors and seizures. These are almost indistinguishable from snail bait poisoning.
- Black Walnuts are toxic. This is a rare tree in Australia as the nuts are not edible for humans either.
- Dogs prone to pancreatitis can get sick from any oily or fatty food, such as nuts. If your dog vomits frequently or goes off their food without good reason, see your vet for a blood test.
- Too much of any unusual food can upset a dog’s gastrointestinal tract. This can lead to vomiting or diarrhoea, but should resolve within 24 hours.
These considerations should also apply to pecans.
Help! My Dog Ate A Walnut
So you drop a walnut kernel and your dog gets to it before you do. What do you do? Answer: not worry too much.
I still would not make a point of feeding walnuts for the reasons listed above. Giving walnut oil is definitely not advised in the same way as any fats or oils. But even if you do deliberately give the odd walnut, you’re unlikely to do harm.
Which Nuts Are Toxic To Dogs?
Of the commonly available nuts, only macadamias are known to be bad for dogs. They are associated with tremors or shaking, but rarely anything worse due to the amount required to be eaten. Therefore, macadamia poisoning is rarely seen by vets.
The main threat is to those dogs that have a walnut tree in their yard. These trees are best either fenced or stripped before the nuts mature, just to be sure. If that’s out of the question, then at least keep the grass short underneath the tree and pick up fallen nuts every day.
