Hi I am looking to use transdermal magnesium spray on my collie

Customer Question

Hi I am looking to use transdermal magnesium spray on my collie dog. As I heard it is good for helping the dog to sleep and with overall general health. Can you confirm it will be ok. My dog is 6 years old and in general good health
my email address if you need it is *****@******.***

Aloha! You're speaking with Dr. Michael Salkin
While excess magnesium usually isn't harmful to our dogs because their healthy kidneys rapidly excrete excess magnesium, supplementing with magnesium shouldn't be necessary unless the following exists:

decreased oral intake or gastrointestinal absorption of magnesium as seen with small intestinal disease causing malabsorption

increased gastrointestinal loss from protracted vomiting or diarrhea

increased urinary magnesium excretion as seen with interstitial nephritis or diuretics

In an otherwise normal dog, the amount of magnesium present in a generic over the counter vitamin-mineral supplement will suffice to provide Snowy will all the magnesium he requires. Adding more in the form of a transdermal spray won't assist in helping him sleep - an unusual problem in the normal dog in any event - nor improve his general health but will ask his kidneys to work harder by eliminating the excessive magnesium from his blood stream.

Please respond with further questions or concerns if you wish.

Hi Thanks for the answer. If I use the spray as a supplement spray rather than putting magnesium in his food would this be OK.

The reason I am interested in using the product is my friend has used in on her older dog as it was a little skittish around noise and she says he seems to have a spring in his step due to the magnesium?

I am asking if I used it, it would it be no worse than putting a magnesium supplement in his water or food?

Best regards

Paul

As long as Snowy's kidneys are healthy, there shouldn't be a problem. I admit that I don't know how effective a transdermal avenue will be. We've found that some of the drugs we'd like to administer transdermally - particularly to hard to treat cats - don't reach effective blood levels. You might make a call to a veterinary formulating pharmacy and ask if magnesium can be administered transdermally to dogs.
