There is some excellent prose and descriptions in this puppy love tale.

She haunted me in that space for weeks, floating over my coffee cup in the mornings, reaching for me across the sheets at night.

The story starts melancholic and somber but then brightens as if the sun parted through the clouds.

On some parts I had difficulty determining who the speaker was. For example,

I looked at her and it felt as if the sun had just come out.

“I tell you what. I’ll take the mutt home with me, but you’ve got to agree to come over to my place and visit, often. You’ve got to agree to come and help me when I take him for walks in the park. You’ve got to help me check him out of this cage right now, and perhaps we could do coffee to work out a schedule. For the puppy, you understand?”

Adding a 'he said' or 'she said' after the first sentence would make it easier to follow. Sometimes this is not necessary because of the flow of the conversation, but when there's a break in that flow, adding this bit of extra information can be helpful to the reader.

This is was an entertaining read. :)
