Yogi is covered in lumps (all biopsies and scans inconclusive). Some growing/hard. Recent sores on his skin where it's red and dry flakey skin comes away when I brush him. He is also growing lots of whaT looks like warts or skin tags. He is limping occasionally on his front leg which has a lump. He has been fine within himself earing and going on slow walks but recently his breathing is getting noisy like whistling also occasionally labored. Please any advice or opinion is appreciated

Thanks for using Petco Pet Education Center, formerly Petcoach! The fact that these biopsies have come back inconclusive does not mean that this is not cancer. Unfortunately, this is very likely an aggressive form of cancer. After seeing these images, my main concern is that this is possibly a tumor arising from one of the ribs or sternebrae such as osteosarcoma for instance. In one of the images I see that there is likely pulmonary nodules which are most likely due to metastasis or spread of this cancer. It is hard for me to advice further without being able to look at more images or know more about the case. I would encourage you to check in again with them as another biopsy could be performed. Also, if there is truly already signs of metastasis, the treatment options and prognosis are also limited. I would mention to them the possibility of being referred to a veterinary oncologist who can look at the case with more details and advice further. I really hope they can help you and your boy!
