If you think your dog has consumed excessive amounts of salt, ensure they drink plenty of water to dilute the salt and contact your veterinarian straight away.

Sunflower seeds can lead to gastrointestinal distress: lingering cases of bloating, constipation, vomiting and diarrhea in dogs can cause inflammation of the stomach which is often caused by items that dogs can’t chew and digest properly such as sunflower seed shells. Dogs with gastroenteritis are often withheld food for 24-48 hours while treatments such as antibiotics and anti-vomiting drugs are given to help settle your dog’s stomach. In rare cases, an unshelled sunflower seed could get stuck in a dog’s gastrointestinal tract and cause a blockage, which can be life threatening.

Is birdseed bad for dogs

In most cases, if your dog hoovers up some birdseed it won’t harm them. However, a large amount of bird seed can cause health issues and there are a few things to be aware of before letting your pet dine with the birds.

Check the ingredients: most bird seed contains raisins or sultanas which are toxic to dogs and can cause kidney failure. Choose a bird seed that contains other ingredients that are safer for canines such as apricots just in case your pooch eats any.

Pick up moldy seeds: if you leave bird seed on the ground for too long it will grow mold which contains toxic chemicals that can lead to liver damage in animals.

Be mindful of bacteria: if your dog picks up dropped bird seed from underneath the bird table there’s a chance that the seed contains bird feces. Bird feces contain harmful bacteria and even parasites that could cause illnesses such as sickness and diarrhea if your dog eats them.

Large amounts of birdseed could cause blockages and bloating: if your dog consumes a large amount of bird seed there is a risk that they could have a gastrointestinal obstruction from the seed clogging up the intestinal tract. This can be extremely painful for dogs and can even end up requiring surgery to clear the blockage.

A simple way to try to stop your dog from eating birdseed is to keep it high up and use a tray underneath to catch any seed that falls off. Regularly collecting any dropped seed and cleaning the area are other ways to prevent your dog from eating any leftovers.
