Senior Dog Becoming Aggressive? Here’s What to Do

Whether this behavior is recent or worsening over time, senior dog aggression can be managed.

Snapping, snarling, and barking incessantly can all seem like aggressive behavior, but it’s often due to pain or anxiety. Medication, supplements and in some cases training, can all make a big difference.

Does it feel like you woke up one day, and your once docile and sweet pup started acting like a character out of some horror flick? Okay I may be exaggerating slightly, but I think you get the picture. On the flip side, it could be his pain or anxiety has been coming on ever so slowly, it was hard to notice until he started becoming aggressive.

what are the reasons for senior dog aggression

Signs of Dog Aggression

There are ways senior dog aggression can manifest itself:

  • Snapping
  • Snarling
  • Nipping or biting you, other family members, friends, strangers, dogs
  • Barking incessantly and frantically

Causes of Senior Dog Aggression

Anxiety

Since this website is all about anxiety, let’s start with this cause.

Dogs can experience an increase in anxiety as they age which could be generalised, or in a specific situation such as when left alone. A dog that always coped well with separation in his younger years, may become very anxious as he ages. Anxiety can also be caused by vision loss, hearing loss, dementia or all three!

Pain or Discomfort

It’s perfectly normal for a dog that’s experiencing pain to lash out. It doesn’t matter if it’s caused by arthritis, hip dysplasia, dental disease or recovery from surgery to name just a few examples.

Some signs your dog may be in pain

  • Whining or whimpering
  • Clinginess
  • Lack of interest in things he used to enjoy
  • Reluctant to go for walks/unable to walk
  • Lethargy
  • Difficulty sleeping or resting
  • Licking one spot on his body
  • Difficulty getting up and lying down

Whether you’ve noticed any of these or just a feeling something isn’t right, I recommend a visit to the vet. Once a diagnose has been made, a treatment plan will be put together to manage the condition(s). Depending on your vet, it can include pain medication, natural supplements, acupuncture and hydrotherapy to name a few options.

Dental Disease

This is a very painful condition, so aggression is certainly understandable.

If your dog has bad breath, is pawing at his mouth, drooling or lost interest in food or treats, take him to the vet right away. If he does have dental issues they can be sorted, the pain will disappear and so will his aggression (if it was the sole cause).

Daily brushing, regular anesthesia free cleanings (often done by a groomer), water additives and dental chews can all help keep your dog’s mouth healthy once he’s had his cleaning/surgery.

Lack of Energy or Mobility

If he can no longer keep up with a younger dog in the home, attempts by the other dog to play can be met with aggression. It doesn’t help if a lack of mobility prevents him from removing himself from an annoying situation. Teach the younger one to stay away, supervise when they’re together and separate them when necessary.

Dog Dementia

Confusion, anxiety and not recognising the familiar are just some of the symptoms associated with dementia. Not only does it cause anxiety, but it can lead to an otherwise sweet natured dog displaying bouts of aggression.

Vision and/or Hearing Loss

Imagine how scary it must be for your dog as he starts to lose his hearing, vision or both. He has no idea what’s going on, and because he is startled more easily, he may lash out before he realises who’s approaching. A once enjoyable ride in the car or a visit to a local café, can all be filled with anxiety.

Here are some ways to accommodate these changes:

  • Calling out and somehow making your presence known before touching him – and that includes telling everyone else to do the same
  • Not moving furniture around so he doesn’t bump into things and get scared
  • Keep the floors clutter free so he doesn’t trip, get hurt and become anxious
  • Try and keep the noise and activity level down for a bit

Brain Tumour

Not common but not unheard of, a mass on the brain can cause a sudden change in personality. A change in behavior, seeming unsteady or a head tilt are symptoms. It could also signal vestibular disease so best to see your vet.

A New Pet

The introduction of a new pet into the home can cause senior dog aggression. He’s anxious because of the change in routine, he may not be getting as much attention/walks as he used to, or the new family member is bugging him. Pay extra attention to him, and monitor interactions. If your senior isn’t feeling well, unwanted attention is the last thing he needs.

How Do You Calm an Aggressive Dog?

Be aware of what induces aggression

Take note of situations when you’ve seen your dog show aggression, and include as much information as you can –

  • Time of day
  • Type of behaviour you witnessed (film it if possible)
  • What your dog was doing right before it happened
  • Was anyone bothering the dog

Being aware of the situations that induce aggression, means there are things you can do to prevent or minimise them.

Take your dog to the vet

Unless you’re absolutely sure what’s causing this behavior, I recommend you take your dog to the vet. Aggression in older dogs is usually down to a health issue, so please don’t adopt a “wait and see” attitude.

Joint pain/mobility

this stroller helps prevent senior dog aggression

If it’s painful for your dog to walk, subtler signs may not have been recognised, so aggression is how he’s communicating that discomfort. Please don’t beat yourself up feeling like you’ve missed something. Dogs are great at hiding pain, but also it can be such a gradual change it’s easy to assume it’s all a natural part of aging.

Medication and supplements can make a huge difference, and so can mobility aids:

♦ Harness – the Help ‘Em Up Harness is super popular, and I’ve lost count of how many senior dog parents I know love it! Visit their website for more information.

♦ Pet stroller – a pet stroller is my favorite mobility aid for my dogs. I use it every day (see picture above), and I don’t know where I would be without it. The ones I’ve linked to are the same style as mine, just a different brand. It’s basic and works best on pavement, but that’s all I need. There are lots of other styles depending on use, and prices depending on budget. Buy on Chewy or Amazon.

♦ Ramp – whether your dog needs help getting into a car or onto the couch, you’ll find a ramp to suit.

♦ Mats on slippery floors – I wrote a whole article on this topic, so rather than repeat what’s already been written, here’s the link – “How to Stop Your Dog Slipping on the Floor

Create a quiet space

Make sure your dog has a quiet space to retreat to, an area that is his where no one will bother him. Whether you want to add a covered crate he can crawl into (leave the door open) or set up a bed in a quiet corner or another room, it’s important to keep him away from stress.

Explain what’s going on to the rest of the family

Let everyone know what’s going on, and together come up with strategies to help your dog.

Play calming music

A CD called “Through a Dog’s Ear” was a sanity saver, when my dog Red was experiencing high anxiety due to dementia. It would calm her down in no time, and reduced the stress all of us were feeling. I had volume 1 which is not available on Amazon, but here is volume 2. Listen to a free, 15 minute sampler of volume 1 on Youtube.

CBD oil

While I don’t believe CBD oil is a cure for everything that ails humans and animals, the success stories I read from senior dog parents I know is compelling, and cannot be ignored. If your dog is ultimately diagnosed with pain or anxiety, CBD oil may be an option, but check with your vet first. See the article below for more information.

Valerian and Skullcap

Another possible aid is Valerian and Skullcap which is used to treat anxiety, if that’s what the aggression stems from. See the article below for more information.
