Question:

Mast cell tumors on a behaviorally difficult dog - when is it the right time?

I'm at a loss here and could really use some advice. My sweet dog, Buster, who's been with me through thick and thin, has been diagnosed with mast cell tumors. He’s always been a bit of a handful behaviorally—reactive to other dogs, nervous around new people, and sometimes even unpredictable at home. We’ve worked on it for years with trainers, but it's just part of who he is now. Vet visits are always really stressful for him, and I’m starting to worry about what the future looks like as his health declines. I'm really torn about when or if we should consider euthanasia, especially when his quality of life starts to go downhill because of the stress of treatments and his already difficult behavior. I love him so much and want to do what's best, but I'm struggling to figure out when the "right" time is, or if there’s a better way to manage all this. Any experiences or advice would be greatly appreciated.

Answer:

Thank you for reaching out with your concern. Managing mast cell tumors in dogs can be challenging, especially when behavioral issues are in play. Mast cell tumors are a type of skin cancer that can vary greatly in severity. The timing for seeking treatment often depends on the tumor's size, growth rate, and any additional symptoms your dog may be experiencing, like itching, redness, or discomfort.



In managing mast cell tumors, consider the tumor's current impact on your dog's quality of life. If the tumor is growing rapidly, causing your dog distress, or interfering with daily activities like eating or moving comfortably, it’s important to consult with a vet soon.



Behaviorally difficult dogs can make vet visits tricky, but there are gentle approaches and even sedatives that can help your pet stay calm during necessary examinations or procedures. At home, keep the area clean and prevent your dog from licking or scratching the tumor to minimize irritation.



Watch for signs such as increased growth, ulceration, bleeding, or changes in energy and appetite, as these could indicate the tumor is becoming more serious.



Let's ensure your dog receives the best care by booking a video consult with Dial A Vet, where we can discuss treatment options and strategies for your unique situation.

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
