@libstrong Yeah, our standard answer has been... get a DNA test to get a bit more certainty. But, who cares really. He is what he is. I love his doughnut bagel tail. He sounds like a fantastic doggie! Smart, affectionate, sticks with you on walks... sounds like an awesome little dude to me. Welcome to forum too!
I am so sorry about your brother. Yes, seems he was meant to be with your family. If you get a chance, record his vocalizations. We really love pictures and videos!
That little guy is soooo adorable! I just love it when Bs 'wag' their tails…... love the markings on him-too funny the you-tube next to all that space stuff! Good luck with Hubble!
