Fiery was like that near the end. She could see a little but couldn't hear. She'd just follow me around slowly and went where ever she felt the need. We started having a few issues in the house as she was getting forgetful sometimes.
The two we have now are on grain free. Found out very early on when Athena was a puppy that she can't do wheat. I guess GSDs have that issue a lot. They get the Kirkland stuff usually since it's a good food, or if I can get a really good sale, Taste of the Wild. Normally they poop once a day. I only give them grain free treats as well. Just have to yell at them to keep out of the chicken food.
Our last greyhound is 14 and their average lifespan is 12-14 years. I have no idea when she's going to pass on. She's like the Energizer bunny, she just keeps going and going. She had a stroke a few months ago and we were ready to put her down, but she was not ready to go and has mostly recovered. She has her good days and bad days, and we can't tell if she's senile or incontinent or both. She wants to go out 6-8 times a day, sometimes right after she gets back in. Maybe she feels the urge to go again, or maybe she forgot that she already did? Who knows. She's always been given a treat after doing her business, but now she'll eat it and then come stare at me again as if she forgot she already had it. She can hold it through a regular night, but if we sleep in sometimes she has accidents (sleeping in is much rarer these days with a toddler). She's been on Proin for bladder control ever since she was put on Phenobarbitol for seizures (greyhounds are freaking expensive!), so we can't do much more if she starts leaving puddles in the house.
I am so jealous of dogs that only poop once a day. All of mine always did 2+, and we feed Kirkland as well. The front yard is a minefield, and I have a hard time finding the motivation to scoop it in the cold rain.
