Diaper rash cream for dogs?

Firstly, I'd like to share with all of you that last night Beau received a $100 donation from a complete stranger! I received the email notification, and I didn't recognize the man's name so I called my dad and looked him up on facebook. To my complete shock, I have no mutual friends with him, he doesn't even live in the same state as I do! I feel so grateful and blessed to have gotten a donation from somebody who doesn't know me... it was purely out of the goodness of his heart. His caption underneath the donation is "Love heals all."... Wow. I hope it does because my love for Beau is unconditional! It is an amazing feeling to know that there are still great people out in this world. So THANK YOU! to this kind soul, and THANK YOU to all of my friends and family members who have donated to Beau! :) Please continue spreading the word!
This morning Beau kept waking me up because he was a hungry boy. I couldn't just ignore his requests so I got up and made him some chicken and black beans. He loved every bite! Then I took a look at him and it seemed that his skin irritation was worse this morning. Although I can never be sure because I can be very paranoid and a bit of a hypochondriac at times. But I swear his lumps and bumps from the Lymphoma looked more red than usual. I considered emailing Dr. Hillers but I decided not to bother her because I know she must be busy at work. To my surprise Dr. Hillers emailed me early this afternoon! The email asked about how Beau is and told me that his blood-work looked good overall but his liver enzymes were high which is likely due to the steroids. I love that she is the kind of doctor to just email to see how her patient is doing! I told her about his skin being so red and asked what I could do to soothe him a bit. I had tried Aquaphor but it didn't really absorb into his skin and he loved to lick it off right away. She said that Destin Diaper Rash Cream would help a because it doesn't get too goopy but it's moist enough to heal. She also said that it has zinc oxide in it too which may help decrease bacteria. Dr. Hillers even uses it on her own dog and she's never seen any side effects! I was thrilled to get her quick response so that I could start treating the problem. I flipped Beau on his back and started rubbing the cream on his most irritated areas. At first he was a confused and squirmy but after a couple seconds he just relaxed and let me lift up his arms to get everywhere I needed to. I'm guessing it felt soothing for him, because his eyes started closing and he kept calm. To my surprise the cream actually smells good! Beau didn't really even try to lick it off and it absorbed very nicely, it didn't just sit on top of the skin! I'll update you in a couple days and let you know if it seems to be healing at all.
To any other pet parent going through something similar to what I am going through, I have a bit of advice- Have an amazing group of friends. I have been struggling everyday. I haven't been going out because I want to be with Beau every second that I can. I would never be able to do this alone. My friends have been amazing. One in particular, Kersten (SHOUT OUT!) who was there when I got the news about Beau's cancer being back. She has seen me cry more than anyone recently, which is not a fun sight. Everyday she asks about Beau and gives me words of encouragement. This is exactly what I need. Kersten, along with all of my other friends, have been so sweet and caring and encouraging. My friends who have donated have especially touched my heart because I know they are just as broke as I am, yet they are reaching out and giving Beau the few dollars they can...that really means so much. A strong support system is key in times like these.
Donations: Stephanie Ayoub, one of my dearest friends donated to Beau's chemo fund today. I love you so much Steph, thank you for helping us out!

An encouraging text from my sweet friend Kylee. She has such a kind heart and I loved waking up to this.

Straight chillin'. You can see some of his lumps on his chest.

He likes to peek through the window.

After I rubbed the Destin's Cream on him..You can see it a bit on his neck.

Relaxed while I try to help his irritation. 

He loves burrowing onto my pillows.

He's not asleep, he just blinked :)
