A very old stray {The Old Fella Story}

The day was passing fast and Old Fella was getting comfortable with his new surroundings. From time to time Richard would venture out to the back yard to visit with Fella, reassuring him he was going to be alright. Richard would sit down next to Fella speaking softly trying to get him use to his voice. Fella would lay there and look around or just get up and wonder off somewhere as if to say “I need some space”. As the sun began to set in the lengthening shadows of the day Fella realized he was in the presents of a gentle man who truly cared about him and his welfare. He felt that he could trust this man to comfort and take care of him so he began to let his guard down and walked over to smell Richard’s hand and then kissed it ever so softly and then looking up for approval. This was the first sign that he had shown of any affection since his rescued.

That evening Fella was allowed in the house with Levi and Izzie. They had all gathered in the kitchen to get some treats. Fella was just following along to see what was going on. Levi began to run around the kitchen barking with excitement making a nuisance of himself. Finally Richard having enough of Levi’s antics turned to Levi and said “Sit!” Then the most amazing thing happened, Old Fella sat! Looking at Richard with expectations of a reward he had a smile on his face and all the while waging his tail. “What the?” Richard said walking over to Old Fella. Pointing his finger to the floor Richard gave the command “Lay down.” Old Fella lay down on the floor. “Sue come here! You aren’t going to believe this!” Sue comes into the kitchen with a puzzled look on her face, “What’s going on?” she asked. “Watch this.” Calling Fella over to him RIchard gave the command “Sit.” Old Fella sat. “Lay down.” Richard said. Old Fella lay down. Sue and Richard looked at each other in bewilderment and then laughed out loud. “What in the world do you think we are going to discover about this old dog before it’s over?” Richard said.

I am not an expert editter or anything so please take my suggestion with a grain of salt, but (and I am in no way being critical of the story, the way it's written is beautiful, you are very gifted with words Richard!) I see some areas where you are teetering between past and present tense. "Old Fella sat", "Richard gave....""Sue comes into" .
