📝 Product Details

From the brand

I’m Diane. My husband and I met and fell in love because we both volunteer at a stray dog rescue.

After a year of marriage, I had a miscarriage and was found to habitual miscarriage, which made us so sad.

The pain of losing my baby made me pour all love into dogs, maybe God thinks that I love these dogs as passionately as I love own baby.

Now we have 4 dogs and often take them out on trips! We are very blessed with these adorable fur babies!
