Biden's rescue pup Major is spending more time in Wilmington as Secret Service emails reveal he bit agents every day for a week along with nipping staff and a White House visitor

Joe and Jill Biden's rescue pup Major is spending more time in Delaware as a new cache of Secret Service emails reveal the German Shepherd bit more people than the White House previously disclosed.

The three-year-old dog bit agents every day for a week in March in addition to nipping staff and a White House visitor.

'As we've stated previously, Major has had some challenges adjusting to life in the White House. He has been receiving additional training, as well as spending some more time in Delaware, where the environment is more familiar to him and he is more comfortable,' Jill Biden spokesperson Michael LaRosa told DailyMail.com on Friday.

'Major may come and go to Delaware, as the First Family often does as well. When he's in Delaware, he stays with family friends,' he added.

The dog is there now as is first lady Jill Biden. 

In March, it was revealed Major was receiving additional training after biting a security official. While there were two incidents revealed, the new information on Friday reveals the dog attacked more people than the administration had disclosed.  

Emails from the Secret Service, received by the watchdog group Judicial Watch under the Freedom of Information Act, reveal the dog actually bit one agent twice, nipped other security personnel, snapped at a staffer who works upstairs in the White House residence, and bit a visitor to 1600 Pennsylvania Avenue twice. 

In the 36 pages of emails, Secret Service staff document over and over again Major's attacks on personnel, where he broke skin, tore an agent's overcoat, and caused a few to seek medical attention.

No names were revealed - neither the victims nor many of those who sent emails about the incidents. The email messages also were redacted of personal information and photos of the bite marks.

But the messages make clear the agents who guard the complex and the first family were worried about Major's biting. 

'He's been an issue lately,' one agent wrote of the dog in March. 

Major was last seen by DailyMail.com at the White House on March 31, where he was on the South Lawn, leashed and led by a staffer, with Champ, the Bidens' older dog who died in June. 

At the time, Major had returned from a training session in Wilmington after one of his biting incidents became public. 

The first couple also told NBC's 'Today Show' at the end of April that the dog was back at the White House.

Jill Biden defended her pooch: 'He is such a sweet loveable dog, he really is.' 

But the emails make clear there were other incidents involving the dog, who the Bidens adopted from a shelter in Wilmington in 2018 and named after their late son Beau, who was a major in Delaware National Guard. 

On March 5, a visitor to the White House was bitten on the arm twice when the dog went after him. 

'Attempting to ascertain severity of injury. Pass holder walked out of and dog made bline to him. Got his arm twice. A group was standing there at time,' an agent wrote.

A residence staffer was also bitten, an agent flagged, simply noting that a dog did it.

'Was it Major,' another agent responded.

'Minor. Did break the skin,' came the response.

'Sorry. Meant was it Major, the name of the younger German Shepard. He's been an issue lately,' the agent answered.

'Dog: Major. Injury: Minor,' the person said in reply.

Over the next few days the agents again raised the issue of Major's biting again and again. German shepherds are known to be territorial, aggressive dogs and protective of their families. 

One wrote on March 6: 'Major attempted to bite SA this evening. He didn't make contact with agent's skin, but did bite a hole through his overcoat. This marks the third day in a row someone has been bitten by Major (Thursday USSS SA & Friday Pass Holder).'

The person added: 'I just wanted you to have visibility. I think it's definitely worth bringing up during Monday's meeting with staff.'

And a Secret Service staffer wrote on March 8: 'We had another dog bite incident this morning. This was the 2nd time SA was bitten. Please see the below write-up and pictures. The 1st picture is from today. The 2nd picture is from 3/1/21, the first time SA was bit. SA was seen by the residence Doc and was referred to the EEOB Clinic for additional care.'

The details about the incident and the photos were redacted by the Secret Service. 

'At the current rate an Agent or Officer has been bitten every day this week (3/1-3/8) causing damage to attire or bruising/punctures to the skin,' the person noted. 

There was a long email chain about biting incidents but not all were described in the released emails.

One person responded to the concerns: 'The dogs are being transported to Delaware and will stay there for an undetermined time. The family will use a trainer they have used previously.'

'Were the dogs sent home because of the biting?' a Secret Service staffer asked. 

A colleague responded: 'Pretty positive.' 

At the time, the Bidens' older dog Champ was still alive although he did not prove a calming influence on his fellow pooch. 

There were also incidents with Major at the Biden's family home in Delaware.

'This weekend in Wilmington, there were 3 minor incidents where Major nipped/ brushed up and nudged Shift SAs,' an agent wrote on March 1. 

Agents were advised to stand their ground when dealing with the dog.

'Panicking or running with only embolden animals so stand your ground and protect your hands/fingers by pockets or behind your back,' the email read.
