I have two shows which I have very brief vague memories of, there both aired in the early 90's and since im in canada, they might not have been aired in the US.
1) This show was a live action puppet type show. I believe there were no humans. I think all the puppets were dogs. The main character was a dirty shaggy dog, brownish stood up at all times. The setting was wierd, it was a house with a garden outside but everything was so dark and dull, It aired in either CBC, TVO or CTV but not YTV.
2) The second show also had to do with puppets. The puppets were all in a spaceship or in outer space and I think at the beginning the captain which i believe was a female puppet would enter through a door and come down steps. lots of songs, they sort of looked like the muppets. they all wore space type suits. This I believe was on an american channel
Help is appreciated
