When jealousy occurs, it is important to deal with your dog's emotions, properly. Introduce your dog and the new puppy on neutral grounds first. This will help maintain the idea that you are their pack leader and you are willing to play with both dogs. They can use this neutral territory to explore each other.
Avoid giving too much attention to one pet over another. Train your dog to feel safe and relaxed in their crate. Make a separate feeding space for multiple animals. Don't pet one of your animals to make others jealous purposely.
While dogs can be very accepting, it may take time to stop all jealous behaviors entirely, so patience is essential for smooth transitions. Dogs that are in emotional distress will typically give these clear signals: Whining. Curled lips.
It can take up to one month for an old dog and new dog to really settle in and accept each other's position in the pack. If you want a second dog, you need to be ready to commit to this process and not panic.
Introduce valuable items like toys slowly
As you see that they're getting along, introduce toys that your older dog doesn't really care about and that are safe for the puppy. Or bring in new toys as long as the older dog doesn't guard them. Have one handler play with the puppy and another with the adult dog.
Illness or injury
If a dog is at all unwell and suffering from injury or illness after giving birth, this can lead to rejecting a litter. Sometimes, mothers can contract mastitis which causes inflammation, pain and discomfort in the teats which will cause her to avoid nursing her pups.
By demonstrating your leadership skills, you instill in both dogs the importance of listening to and following you. Now both dogs have something in common; both see you as the boss. Let your older dog see good things happen when the puppy is around. Give both dogs lots of treats and tons of praise for staying calm.
The amount of time each individual pet needs to adjust to their new homes will vary, but the 3-3-3 rule helps give an approximation of what new pet owners can expect. The 3-3-3 rule refers to the first 3 days, the first 3 weeks, and the first 3 months after bringing a shelter animal home.
Dogs are inherently social animals that live well together in groups, but that does not mean that all dogs get along. Most dogs will welcome a new sibling, but it is not always smooth sailing. The furry family member you have now will face many changes when a new dog enters the picture and may feel a bit displaced.
Introduction of a New Pet
Bringing home a new puppy or another adult dog can trigger jealousy in your dog, and they may show signs of aggression toward the new addition.
Indications that your dog is feeling jealousy may include whining or vocalizations when you show affection for another animal or a person, pushing another animal out of the way to get attention for themselves, refusal to obey, and sometimes even signs of depression and a loss of appetite.
Jealous or possessive behavior can be changed once you know why your dog is acting a certain way. Both behaviors can turn into aggression if they're not addressed and corrected. Change is not in a dog's vocabulary and they prefer nothing changes in their lives.
You've finally introduced the puppy into the home, but now you're wondering, "Will my dog ever accept this puppy?" Your dog likely will get used to the puppy - and may even learn to like them! - if you're thoughtful and respectful about their inhibitions. Supervise carefully. Caution is important.
It may take several weeks for the two dogs to get used to each other, so patience is required. But most of the time, dogs are accepting of other dogs, often welcoming the companionship. It's just a matter of an owner setting expectations and being consistent.
Second Dog Syndrome
As humans, we are bound to forget all of the time and effort it takes to raise a puppy right. All too often, a second dog joins the household and the expectation is that they will behave as the existing dog in the home does, so they are often given the same freedom right off the bat.
There isn't research for dogs, as there is for cats, that show how long it takes dogs to adjust to each other. Phifer, however, says that two to four weeks is usually enough time to know if dogs can be friends. During the adjustment period, you want to see these behaviors: Fewer grumpy moments.
You can survive for 3 Minutes without air (oxygen) or in icy water. You can survive for 3 Hours without shelter in a harsh environment (unless in icy water) You can survive for 3 Days without water (if sheltered from a harsh environment) You can survive for 3 Weeks without food (if you have water and shelter)
When you see someone interesting to talk to, you have three seconds to walk up and say hello. Wait longer and you'll either overthink it and screw it up or overthink it and never approach. Not sure what to say? It doesn't matter.
Very few dogs coexist without disagreements. A stare, a lifted lip or a growl is a normal dog signal that he's uncomfortable with something another dog is doing. Often the recipient of these signals will stop and move away—this is appropriate. There is likely to be some of this at first.
You can introduce your dogs before they meet using scent swapping. One way of doing this is by taking a blanket, toy or something else with the dogs' scent on it from each dog. Place it in a safe and appropriate area of the other dog's environment, like in the garden, and allow them to investigate it at their own pace.
Dogs will typically react aggressively towards other dogs for two reasons, fear, or they believe the other dog represents a threat. Your dog may perceive a threat to their status or safety, or they may even be protecting you against an apparent threat.
Your dog's behavior may not have anything to do with the other dog at all. It could be all about you. Some dogs are more protective and possessive of their humans than others and simply do not want another pup coming in between you. This is common in dogs that are overly coddled and have a lack of leadership at home.
