Inu ni Nattara Suki na Hito ni Hirowareta.

pretty self explanatory  

Both are R+ grade ecchi about a dog lusting for his mistress, from the animal's perspective. Both feature low angle POV camera shots, off commentary by the dog, and nopan shots. I guess that's in line with the overall bestiality theme. 

Both are R+ grade ecchi comedies through the eyes of pet animals who want to get physical with their mistresses. In Inuhiro it's a dog while in Juliet a Scottish Fold cat. Both emphasize low camera angles and no-pan backside fetish in their ecchi part - I guess that's in line with the overall bestiality theme. 

Both anime feature a dog named Pochita. 

Both are reincarnations of pets but the genre is slightly different.
