My dog Beau needs anal gland surgery

Hello

My best friend and I found out he needs anal gland surgery at the end of January. He has been in pain and uncomfortable for a few months, not wanting to go for long walks or exercise for very long. He looks at me with sad eyes as he scoots across the floor. The vet expressed a few days ago and said we need to get them out of there so scheduled surgery. I am a single dog mom working two jobs at the moment. Any help is greatly appreciated. Thank you.
