Reasons Dog Is Acting Strange And Sniffing Everything
1. Change in Environment
It starts with a change in the dog’s environment.
A dog will begin to sniff everything when it notices a difference in its surroundings. This can be a number of things and is not limited to one particular change.
For example, some dogs will respond as soon as a stranger walks into the room. While other dogs are going to perk up when they smell a food source enter the property.
This is unique to each dog but most will sniff when they see this type of change in their environment. It is natural for the dog to observe with its nose and that is something it will do wholeheartedly.
Some dogs do get used to these changes after a while but others don’t. There is nothing to be concerned about as long as your dog is healthy.
If they are just sniffing around and poking their nose everywhere then it is a sign they are being inquisitive.
Just pay attention to where the dog goes and you will get your answer. Most will simply sniff their way to a specific spot where the “change” has occurred.

2. Curious
Dogs are curious animals.
They will want to use their nose to learn more about what is happening around them. It is rare to see a dog ignore everything and just assume their environment is good to go.
Most will always want to smell the changes and see whether or not it is safe for them.
This curiosity can lead to situations where the dog acts strangely and sniffs everything. You don’t have to worry about this as it is normal.
If you are worried about the dog, you can train its nose to calm down.
The best way to do this is to use a sniffing mat. This will help hone the dog’s ability to smell and will ensure it calms down when there are changes to its environment.
It will be a long-term process but one you can work on to keep the dog sharp.

3. Anxious
Anxiety is something to account for as a dog owner.
Your dog might be anxious about a change in its environment. This is often the case when an adopted dog comes home and is adjusting to its surroundings.
You will notice the dog act strangely and sniff everywhere. This is their way of getting acclimated to their surroundings to the best of their ability.
Your goal should be to make the house as welcoming as possible.
This goes for dogs that are noticing small changes indoors. This can even include moving the furniture around from one place to another indoors.
Even these types of changes can cause a dog to sniff around.
