If Dogs Get Into a Fight
Despite all your efforts, your resident dog and new foster may get into a fight. It can look and sound very scary but is usually mostly bluffing.
What to do:
Make a really loud noise (a soda can with coins in it works great) to redirect their attention
Separate the dogs immediately
Keep them separated for a bit to cool down
This does not mean the dogs hate each other or that the foster is aggressive. Just like people, dogs can get heated and overstep boundaries.
Remember: your resident dog is also adjusting to this change and may be protecting their home and resources.

Resource guarding is when a dog protects items they value—food, toys, bones, spaces, or even people. This is not dominance or bad behavior; it's a natural canine instinct. Dogs were bred for thousands of years to guard things. The good news: you can manage and improve it with training. Signs of Resource Guarding:
Stiffening or freezing over an item
Hard stare or side-eye
Growling, showing teeth, or snapping
Positioning body over the item
-
Remove all triggers initially: No toys, bones, or high-value items in communal areas during the first few weeks. This prevents incidents while you assess the dog.
Feed separately, always: Resource guarding often appears or worsens around food when new dogs enter the home (see Tip 3).
Learn what they guard: Make a list of what triggers guarding, when it happens, and how intense the behavior is (head turn, stare, growl, snap). Note the distance at which it happens—does the dog guard when you're 2 meters away? 10 meters? This helps you create a training plan and discuss with coordinators if needed.
Find high-value rewards: Pick treats worth MORE to your dog than what they're guarding. If they won't trade, you need a better treat (stinky cheese, hot dog, rotisserie chicken), not more force.
Start small with low-value items: Begin with things your dog doesn't care much about (an empty food bowl, a boring toy). Practice 'Drop it' or 'Leave it' with a high-value treat as the reward. Once they drop the item, reward them AND give the item back sometimes. This teaches them that 'drop it' doesn't always mean losing their treasure forever.
Build positive associations with your approach: When your dog is eating from their bowl or playing with a toy, approach calmly and drop an even better treat nearby (without taking anything away). Walk away. Repeat this over several days. They'll learn that you approaching means good things happen, not that items get stolen.
Never punish guarding behavior: Punishment makes it worse. If your foster is guarding something, walk away. Remove yourself from the situation. Come back when they're calm and work on training separately.
Trade, don't take: When you need something back, offer something better in exchange. Always use the 'trade' method rather than forcibly removing items.
Supervise bone/chew time: Only give high-value chews when you can supervise. Remove them with a trade before you stop supervising. This prevents guarding incidents when you're not watching.
Train in isolation first, then gradually add distractions: If you have multiple dogs, practice 'Drop it' and trading with the foster alone first. Once they're reliable, practice with other dogs at a distance. Gradually decrease the distance over time. Dogs don't generalize well—they need to learn the behavior in different contexts.
Allow appropriate dog-to-dog communication: If your resident dog grumbles at the foster for getting too close to their food or bed, that’s normal communication. Not all growling is a problem—it’s how dogs set boundaries.

If your foster shows intense guarding (hard biting, won't accept any trades, guards multiple items aggressively), contact your foster coordinator immediately. A qualified behaviorist may be needed. Resource guarding in foster dogs often improves with time, routine, and realizing resources are abundant—but safety comes first.
DO NOT:
DO NOT reach into a crate with a dog and a bone. If you need to get the dog out and they’re guarding something, coax them out with a very high-value item like cheese, salami, or hot dog. Once they’re away from the crate, you can safely retrieve your item.
