Greg and Taylor adopted Dobs sometime in 2013. When asked what breed Dobs is, Greg responded saying, "He’s like a dalmatian and a terrier… if that’s even possible. That’s what the foster parent said" (Source)
In the first year after adopting Dobs, he appeared with LeeLu in many of Greg's videos, including his "Dog Thoughts" video series. In the last year or so, both dogs have not been featured as much in Greg's videos.
