Toby was enjoying his day out with his humans, little Robbie was running around excitedly, sniffing everything and marking his territory all over the place. Megan was trying to keep an eye on him as much as she was attracting the other male humans since she was in heat, which Toby knew meant he'd have to keep a close eye on her here to prevent any unwanted breeding.
"Hey Toby!" He heard someone call him, and looking over, it was Dean, a Great Dane with his human, Kieth.
"Hey Dean." He nodded at Kieth, "He ready to breed?"
Dean nodded, "Yep, call yer girl over and we can get started."
Turning out to the rest of the human park, Toby called out " Megan! Come here girl!"
Hearing her owner call her, Megan ran to Toby, her larger breasts causing some unwanted momentum as she ran, but she was able to handle it. "Arf! Arf!"
Toby guided her over to Kieth, who'd perked up once he'd smelled that Megan was in heat, "Alrighty girl, make us another baby." As the two owners allowed them to start sniffing each other, Toby started crunching the numbers, Megan and Kieth were both purebred gingers, so their offspring should easily fetch a good $4,000 or so.
"Yip!" Megan squeaked out as she was mounted in plane sight of the whole park, but not caring a bit.
"Bark! Bark!" Robbie barked excitedly at seeing Kieth, he was a great playmate, tolerating the younger human's energetic behavior as much as his owner and mother.
"Whoa there boy!" Toby said as he grabbed Robbie's collar, "Let's let your mom and Kieth finish up, alright?"
