I am wondering what's up with the dogs. In Season 5 Tina, Peter's Great Dane and Spit, Brianna's rescue dog vanish. In Season 6, Norman, Peter's other Great Dane and Carl, Sol's Jack Russell terrier is replaced with another canine actor which seems much younger, looks different and because of its youth has not yet developed the original Carl's acting chops. It's always disconcerting when characters either disappear without explanation or are replaced with other actors. Did I miss something?

In Season 1, Episode 2, "The Credit CardGrace says Robert's mother was Irish, but she dies much later in the Series. And in Episode 4, "The Funeral," Robert's sister, Lydia, is thankful that their father is dead so he didn't find out about Robert's being gay, but, again, no mention is made of their mother.
