I just noticed this lump on my dogs neck. Any idea what it could be? He's about 7 and has had a terrible heart mumor since we adopted him as a puppy so I'm worried the vet will want to put him under to remove it and it'll be dangerous for him. Help!

The lump looks like it may be a possible skin growth or even abscess (infection under the skin). Skin growths tend to be benign, however it is best to have the area looked at by your vet. Your vet can likely take a sample of the area without sedation/anesthesia for testing to see what treatment (if any) needs to be done. Your vet can also examine Luke and perform any bloodwork if needed to determine if it would be safe to remove the lump under anesthesia, if needed.

Thanks for using Petco Pet Education Center, formerly Petcoach. Discuss your concerns with Beans vet. Preanesthetic work up such as blood work and cardiac ultrasound/X-rays etc can help assess risk and develop a plan for his optimal safety in surgery. The mass could be malignant or may also be a cyst or benign tumor. Removal and histopahtoligy is the best way to determine what it is and may be curative in the process.
