HINTS FROM HELOISE

Dear Heloise: You shine a light on service dogs quite a bit; allow me to tell you about mine.

When people think of service dogs, they probably think of a dog who helps a blind person or someone who has mobility issues and uses a wheelchair. And yes, those dogs are out there. But my dog, Stella, helps me with my diabetes!

Stella is trained to detect hypoglycemia, or low blood sugar. When my blood sugar is low, the smell of my breath changes and I can start to perspire a lot.

She will sense this and prompt me with a paw or a nudge to treat my blood sugar while I am still able to do so.

She can also sense if I start to feel lightheaded and act like I might faint, also symptoms, among others, of hypoglycemia.

Cayla, I’m so happy you have Stella, a diabetic service dog, also called a DSD. Here’s the thing — a dog’s sense of smell is acute, to say the least.

A human has around 5 million olfactory cells; a dog can have as many as 220 million! This means the dog’s sense of smell can be 1,000 times sharper than a per

son’s. This is necessary to detect those changes in the smell of your breath and/or the smell of your sweat, which may indicate your blood sugar is dropping.

Send us a picture of Stella, and we will make her Pet of the Week on www.Heloise.com!

Dear Heloise: Reverse osmosis, what is it? The label on my bottle of water states the water comes from the public water supply (I assume that means the tap) and it’s purified using reverse osmosis and enhanced with minerals for taste. Please decode.

— Gerry B. In D.C.

Gerry, here’s a Heloise high-five for reading those labels! Let’s look at bottled water. The “public water supply” is, yes, the municipal water from your city, but not straight from the tap.

“Reverse osmosis” is a filtering or purification process that won’t allow anything larger than a water molecule to pass through. A water molecule is EXTREMELY EXTREMELY small.

The minerals used for taste are typically calcium chloride, sodium bicarbonate and magnesium sulfate, but can vary.
