Help Gotti Webtser get Lump diagnosis

Hello this Gotti he is a 5 month old Cane Corso puppy who is a sweet, loving, and giant good ball. my spouse and I decided that we wanted to get a puppy and when we came across him we knew he weather perfect fit. As soon as he got home he was attached to my hip he loves to follow me everywhere, chase bugs , nap and do tricks.

Unfortunately on September 4, 2026 we notice he had a fluid filled lump on his neck so we took him to the vet to see what it was they drained it and thought it was a hematoma caused by rough playing. From that point on it keep refilling after getting drained two more times. he just had surgery on 9/11/2026 which they removed a mass that we have no idea what it is or how it came about.

Gotti is such a fun loving puppy who makes anyone melt when he walks into a room. Between him coming up to you for kisses and pets. He loves to make sure everyone that is around him is feeling okay. He is more than a companion to me, he is more of my child in my eyes. He has helped me in my recovery journey while dealing surgery on my hand. He has brought joy to my life that I never knew was there

We would really appreciate the help with being able to afford to send the tissue sample out from his surgery to the lab to discover what this lump possibly was since most of the vets we have seen have never seen something like this in a puppy.
