Prosecution + pets in the house at the time of the murders

On the night of the shootings, Erik was questioned by sergeant Edmonds and expressed his upset about needing to find his little black dog. Was this Velvet? or maybe the dog Glenn Stevens testified about that he got with Lyle called Muncie? I know Tristess and Chipper 1, the ferret weren’t alive at this time, but what about the other 2 Chippers? There was also a dog called Rudy who I think would’ve been alive in 1989 along with Muncie and possibly Velvet. Has it ever been disclosed what happened to the pets, and if they were in the house on August 20? If the pets weren’t home that night and had been brought to a relatives or friends, could that have been useful for the prosecution? With that information, the prosecution could’ve argued that the brothers didn’t want the pets in the house and intentionally removed them, alluding to premeditation. If the little black dog was staying elsewhere, Erik would’ve known that, but I suppose that in the emotional state he was in, he likely wasn’t thinking rationally.

edit: thanks to your comments, 2 dogs were found in the house! i also realized that when erik was speaking to sergeant edmonds, he obviously wasnt supposed to have been in the house. so he did know where the dogs were but didn’t say that, because then people would know he had been there
