Hi! New and curious your thoughts on Doggie DNA Tests?

Hello all! :wave: New to the forum, just adopted a little rescue last month and named him Wesley. Was told at the shelter that he was a Westie mix which I thought was odd since I had not seen many Westies around my part of KY. But was told he came from another part of the state. I was curious what he was mixed with and wanted to know about how large he would grow to so I bought one of those mix breed DNA kits. Esp. since at 3 months he was around the height of a small full sized terrier all ready.

The results just came in yesterday and I was taken back a little. Results said on one side he had a bichon / newfoundland mix and on the other a chihuahua / cocker spaniel mix. I thought it was really odd because not really sure how a bichon / newfoundland mix would work? LOL being like a 10lb versus a 100lb dog?

Anywho I knew the test was prob a long shot but was curious if anyone else had experience with wrong results? Or if anyone had any weigh ins on what his mix may be? Is a newfie / bichon mix even possible? Very curious since the shelter said they were 100% sure the mom was a Westie and just didn't know what dad was. Looking at the photo below do you think that the test is right? Or should I contact them and ask them to send a follow up test or something? Really more for my curiosity, as far as I'm concerned he's mixed with 100% cute and 100% awesome but still wondering how big he will grow.
