Common Anxieties of Rescue Dogs: Identifying & Treating Problem Behaviors [Infographic]

rescue dog anxiety

It goes without saying that any rescue dog has experienced his fair share of hard times, whether he was abandoned, neglected, unable to be cared for by his family, or worst-case scenario, the victim of abuse.

More often than not, dogs that have spent any amount of time in a shelter are more prone to developing certain issues, including anxiety disorders, destructive behavior, and other physical manifestations of fear or distress.

While the majority of these behaviors can be corrected with adequate knowledge, love, patience, time, and occasionally the assistance of a professional trainer, it’s important to recognize the five most common types of anxiety in your four-legged friend so that you may help him acclimate to his new surroundings.

“I’m Scared!” – Fear and Anxiety

Just because your new pal is out of the confines of a shelter doesn’t mean he’ll automatically feel relaxed or show his true personality from the get-go. Most dogs are traumatized and stressed out to some degree upon arriving in their forever-home, and will need a good deal of time to get used to everything, including you.

Give him time to feel things out, as he may show signs of uncertainty, panic, fear or anxiety – remember, he’s still trying to figure out if he’s in a ‘good’ or ‘bad’ place. When you first get him home, let him know he’s in a secure environment by giving him plenty of space – experts suggest setting up his bedding, toys, food and water close enough where he can still see and hear everyone, but a safe distance away for you and your family.


You may want to use a crate with comfy bedding and cover it with a towel or blanket for added darkness and warmth, as many dogs actually find crating comforting – each dog and breed is different, so it’s worth experimenting in the beginning to see if it’s a good fit for your pooch.

He may hide for a while, but give him time – eventually he’ll come out. Don’t force him to socialize; in this case, patience really is a virtue. Let him come to you when he’s ready, even if it takes a couple of days. You can offer him treats, and reassure him in a calming voice that he is safe. If you’re concerned that your dog’s anxiety hasn’t improved after several months, you may want to bring him to your veterinarian for a complete physical to rule out any medical conditions.

Helpful tip: Dogs don’t always like hugs – in fact, if you shower your dog with too much affection too soon, it might stress him out even more, especially if he’s a recent rescue. The best advice? Let him come to you when he’s good and ready.

“Hands Off My Food!” – Food Aggression

Chances are your furry friend had to battle it out when it came to chow time in the shelter, so he’s probably not used to having his own bowl for drinking and eating. Since he’s unaccustomed to the new dining arrangements, he may not understand the concept that no one is going to take his dish away from him, and may react badly if another dog or person gets too close to him while he’s eating.

If your dog is showing signs of aggression, including growling, baring his teeth, snarling, lunging or even biting during his mealtime, chances are he’s still feeling insecure that his food might be in jeopardy or taken away.

Reassure him by moving his bowl to his crate, the bathroom, or another small enclosed area (such as the garage, porch or laundry room) and don’t disturb him until he’s finished eating. Over time, he’ll realize that he doesn’t need to guard his food.

Helpful tip: When it comes to meal-time with your pup, consistency is key: at the heart of food aggression is your dog’s anxiety over his supper. Keep it simple and feed him the same time every day – dogs have an amazing internal clock and crave rituals and routine. Creating a regular feeding schedule will help alleviate his anxiety while curbing his aggressive behavior.

“That’s Mine!” – Resource Guarding

Similar to food aggression, resource guarding is a canine behavior that exemplifies a dog’s ‘ownership’ over ‘his’ things, such as toys, food, and even people. This sort of possessive behavior is commonly recognized in rescue dogs, particularly because they were forced to share (and often compete) for everything in the shelter, including the affection of a human being.

Once you bring your dog home, he may attempt to guard you from another pet, family member or visitor – in his mind, you belong to him and he doesn’t want to share or even let anyone near you (he may also have a favorite toy that he is overly possessive of).

If you notice signs of resource guarding, fear not; there are certain behavioral techniques you can use to correct the issue. The moment he begins to show signs of this behavior, remove his access to the catalyst, including toys, beds, food, his blanket, and people. For example, if your pooch is curled up next to you on the couch but then begins barking when your spouse enters the room, put the dog on the floor immediately.

After repeatedly being removed from a favorite object or person, he will make the connection that this sort of behavior is undesirable. However, if the problem persists, you may wish to consult a professional dog trainer for expert assistance.

Helpful tip: It’s especially important to bond with your rescue dog in the early phases to develop trust and build a strong relationship. This will happen naturally as you create rituals, get to know one another, establish boundaries, and of course, show them affection. However, how you react to their misbehavior is crucial: physical punishment is never an option, neither from an emotional or humane standpoint.

Besides the potential to harm your beloved pet, you can permanently damage the bond you’ve created. Research proper methods to discipline your pet and educate yourself as a fur-baby parent; if you need resources or assistance, contact your vet or a licensed dog trainer for professional guidance.

“I’m Marking My Territory!” – Leg Lifting

It’s normal for your dog to want to thoroughly explore his new digs, including sniffing every square inch of your home and property. However, he may be tempted to mark his territory, particularly if he smells another dog. This behavior shouldn’t be confused with being housebroken: dogs that have been trained properly may still mark their turf.

So what’s a frustrated pup-owner to do? Experts suggest eliminating this behavior by spraying the dog with water when you catch him in the act. It won’t hurt him, but most dogs dislike it and will stop mid-mark. The key to success for nearly every behavior-correcting exercise is repetition:  eventually your dog will learn that this sort of thi
