Cosmo is 4 months old (17 weeks)… he tries to eat everything. He ate dirt yesterday, My step mom years ago had a beagle, Snoopy.. he was fat. Lol. Now I know why. But he was different looking than Cosmo. I think my girlfriends dog is going to be taller. This dog loves to jump.. heres an example- I have a wheelchair (exciting) next to my bed, and he will jump over the chair onto my bed. He gets air. ..and then he bites my elbow.
