grann of 6

I have 2 dogs, a great dane and a rottweiler mix. Heidi and Gus are both rescues. Heidi, the great dane, was rescued from a puppy mill. She had at least 4 litters of pups by the time I got her at 4. Gus was picked up as a stray at 5 months old and adopted out twice and returned till I got him at 18 months old. They had separation anxiety when I first got them; tore up every pillow in sight whenever I left the house. They now are loving, gentle members of the family. I also have a fish tank with several fish; just lost my beloved Tiger Oscar last week. He was over 5 years old and 12" long. He must have weighed 3 pounds. The dogs don't go into my sewing area (my basement). They won't climb the stairs. Heidi is almost 8 and Gus just turned 6.
