Can Some one help with My Baby Girl Valentine

[Valentine&Ryan]

I woke up today and noticed a big lump on her back side right above her tail. I is filled with Liquid and is about 5 inches wide. She seems to be acting normal I just have never seen something like that on her before. She is also in heat . She is 5 years old . If anyone knows what I can do I would deff. appreciate it. Thanks

I would take her to Vet just to make sure everything is okay.

i would get her to the vet ASAP. theres a lot of bad things that it can be, especially with an unspayed female.

Vet is the best solution to that...to have a reliable and clear answer...
