Rachel Zegler stresses out as her pup's health deteriorates

Rachel Zegler took to Instagram on Sunday to plead for the public’s help in a bid to help her beloved pup, Lenny, who is battling a mysterious illness.

According to her, she reached out to the public as she had lost all hope.

"Okay I am turning to Instagram solely because everything else had been a dead end folks. Sweet Lenny has crazy diarrhea and a loss of appetite and nothing is helping."

"We have been to the vet twice, we are having our proviable, mom has made chicken and ice galore, and no dice."

"We are now trying an appetite stimulant and an anti-diarrhetic to try to get him to eat and settle his tummy. He has never been like this before so I am really, really stressed. Energy levels are normal, he is playful, nobody feels any masses in his tummy. We are drinking water and other wise seemingly good. Unfortunately this comes 48 hours before we need to fly across the ocean. Anything would help."

Her second snap from her story read, “Truly if one more vet tells me to just wait it out whilst he is quite literally in so much discomfort and spraying all over my apartment with such urgency, I am going to pull my hair out."

"That being said I am very thankful for everyone who has helped out little Lenny thus far. Its just so frustrating."

Her latest story picture a while ago said, “Hi y’all – thanks for the help in the DMs we are at the ER getting a GI tract ultrasound, some bloodwork, and some intravenous medicine for nausea! The bubba is still in such high spirits, tail-wagging, alert, wanting to meet everybody, etc. Still seems to have no interest in food, unfortunately, but he’s drinking water!"

"I am trying not to pull my hair out in the midst of all this! Thanks for your help and your endless love for my sweet boy."
