Question:

Dog ate vitamin D supplement does she need immediate care?

I'm honestly a bit panicked and could really use some advice. My 3-year-old golden retriever, Luna, managed to get into my vitamin container and I'm almost certain she ate a vitamin D supplement. I'm worried because I've read that too much vitamin D can be toxic to dogs. She seems fine at the moment, just her usual playful self, but I'm concerned about any delayed effects. The pills are the 5000 IU ones, so not exactly low dosage. It’s late here, and the vet clinic is closed, but there's an emergency animal hospital about an hour away. I'm not sure if I should rush her there or if this can wait until morning. Any thoughts or personal experiences would really help ease my mind right now. Thanks!

Answer:

Hello there! It’s understandable to be worried when your dog gets into something she shouldn’t have, especially when it involves supplements. Vitamin D is essential, but dogs can get sick if they consume too much.

Ingesting a small amount might not cause harm, but a larger dose can be toxic and lead to problems like vomiting, loss of appetite, increased thirst, and urination, or more severe issues like kidney trouble. Please keep an eye out for these symptoms over the next 24-48 hours.

For now, make sure she has access to plenty of fresh water to help her body process everything. If she starts showing any signs of distress, such as vomiting, diarrhea, lethargy, or any unusual behavior, it’s important to seek veterinary care immediately.

While it might be nothing serious, it's always best to err on the side of caution when it comes to potential poisoning. Since I can’t see her in person, I recommend booking a video consult with a Dial A Vet professional. This will give you peace of mind and ensure she gets the right care if needed. Take care, and I hope your pup feels well soon!

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
