Have you recently noticed your rescue dog behaving differently than when you first brought them home? Our dogs' emotions and behaviors can certainly fluctuate over time. Here's what's likely going on.
Comfort vs. Behavior
It's no secret that the common advice amongst dog trainers is to give your rescue dog time to acclimate, keep stimulation low, and allow time for decompression.
While that's all true, what they don't tell you is that once your dog does decompress and become more comfortable with their new environment, you will likely see behaviors you didn't see at the onset.
This is because dogs in a new space aren't necessarily confident enough to act on their impulses until they get more comfortable with their surroundings and the people around them.
So while comfort is the goal, it's important to keep in mind that the behavior or personality your new dog first shows is likely to change within a few weeks. Here's how to tell normal adjustment from a real problem.
What to Observe & Reflect On
A few questions to reflect on during this seemingly sudden shift in their behavior:
Is this a new behavior, or something we've seen before?
What are we noticing right before the behavior? Is there a specific trigger?
Does the behavior happen everywhere, or only in certain situations?
How does this compare to what the shelter or foster communicated to us?
Has anything changed in their environment or routine?
If this is new or escalating, are we equipped to address it, or do we need professional guidance?
When It Makes Sense to Reach Out to a Professional
Dog behavior issues typically don't resolve themselves with more comfort, affection, or freedom. In fact, those things can sometimes make the issue worse by accidentally reinforcing the behavior.
For example, if a dog is growling at someone coming through the door while being pet and hearing "It's okay," they're not necessarily interpreting that reassurance the way we intend. Instead, the attention may inadvertently reinforce what they're already doing.
This is where professional guidance helps — especially if the behavior is escalating or becoming dangerous to others, whether it's immediate family or an occasional unsuspecting person. The sooner you bring in support, the easier the issue is to redirect.
What Professional Guidance Looks Like
With the right guidance, these issues can be addressed through clear routines and communication.
For example, instead of petting your dog while they rush or react at the door, guiding them to their crate or a raised boundary such as "Place," and reinforcing duration (e.g., a waiting period before being released), builds an increased level of impulse control — but also trust in your relationship.
These are all strategies that can lessen frustration and effectively interrupt unhealthy patterns of behavior.
In Closing
A rescue dog does need more time, comfort, and a longer acclimation period than most dogs. However, observing early signs of behavioral issues and addressing them proactively can help keep your dog happy, healthy, and successful in your home.
